Spellweavers Archetype Redux

[encapturer]

First, the lore behind these monsters:
Spellweavers... a sect of magicians who cast various spells using magic lingering in the environment. They create little magic of their own, and have to rely on assistants and bodyguards to generate magic. However, with enough mana to play with, Spellweavers are all but unstoppable.

Second, the general playstyle:
Basically, I want this archetype to focus on momentum. A single spellweaver caster won't do much. A spellweaver generator will only serve to needlessly collect mana tokens. Both together... now you're getting somewhere, since you're able to generate mana and use it. This will be backed by spells and traps that use up mana (and also require a spellweaver caster to be on the field, so a generator is still useless on its own). And with the more mana they collect, the more powerful the spellweavers become. Weaknesses include the generators, which collect the mana counters, and the casters, which use the mana. If the generators die, the mana goes with them, and if the casters die, alot of options are cut. Also, they are not of one unifying type or attribute, and it should be tough to swarm.

Third, the requested input:
Go ahead and rate if you want, but I need to know a few things. The first time I posted this set, it was said to be able to set up OTKs easily and is generally overpowered. Seeing as I tried specifically to make OTKing with these cards hard, this caught me off guard. So, I need to know potential OTKs since I don't know every card in the game. Similarly, any swarming exploits and the like would be nice to know. Suggestions are nice, as well, since I still think this archetype is almost too slow.

Lastly, the cards:
[spoiler='Spellweaver Generators']
Spellweaver Guard
Warrior/WATER/Effect Level 4/700 ATK/1900 DEF
When this card is summoned, place 3 Mana Counters on this card. If this face-down card is attacked, flip this card face-up, end the battle phase, and place 5 Mana Counters on this card.

Spellweaver Hound
Beast/EARTH/Effect Level 4/1800 ATK/1500 DEF
When this card destroys another monster by battle, place Mana Counters on this card equal to the level of the destroyed monster.

Spellweaver's Harvester
Machine/FIRE/Effect Level 2/900 ATK/0 DEF
Once per turn, you may remove from play a spell card in your graveyard, and place 3 Mana Counters on this card.

Spellweaver Soldier
Warrior/WIND/Effect Level 6/2400 ATK/2000 DEF
During battle between this attacking card and a Defense Position monster whose DEF is lower than the ATK of this card, inflict the difference as Battle Damage to your opponent. When this card deals battle damage to your opponent's life points, place Mana Counters on this card equal to the damage done divided by 400, rounded up.

Spellweaver Golem
Rock/EARTH/Effect Level 7/2600 ATK/2600 DEF
When this card is tribute summoned, place Mana counters on this card equal to twice the amount that were on the tributed monsters. When a card with Mana counters is removed from the field, place Mana counters on this card equal to the amount that was on that card. When this card is removed from the field, distribute Mana Counters equal to half the amount on this card to face up cards on the field.

[spoiler='Spellweaver Spells and Traps']
Note that the only spellcaster "spellweaver" cards are the ones in the 'caster' group. and thus are slow at generating mana on their own.

Spell of Protection
Continuous Spell
If you do not control a spellcaster "spellweaver" monster card, destroy this card. During your standby phase, remove a Mana counter from the field for each moster you control, or this card is destroyed. As long as this card is on the field, if any of your monsters would be destroyed, you may remove Mana Counters from the field instead, equal to the total levels of the monsters that would be destroyed.

Spell of Flames
Normal Spell
Your opponent takes 800 damage. If you control a spellcaster "spellweaver" card, you may remove any number of Mana Counters from the field and your opponent takes damage equal to 100 x the number of Mana Counters removed.

Magical Zone Beta
Field Spell
If you control a spellcaster "spellweaver" card and Mana Counters are placed on a "spellweaver" card, except by this effect, place another Mana Counter on that card. If this card is removed from the field, remove this card from play and place a mana counter on every card you control.

Spell of Knowledge
Normal Spell
Activate this card by removing 10 Mana Counters from the field, while you control a spellcaster "spellweaver" card. Draw two cards.

Spell of Counter
Counter Trap
This card can only be activated if you control a spellcaster "spellweaver" card. Remove 3 Mana Counters from the field. Negate the activation of a spell card and destroy it.

Magic Overdrive
Continuous Spell
Spellcaster "Spellweaver" cards you control that activate their effects once per turn during your main phase can activate their effects twice per turn during your main phase.

...so yeah. I want tips and specifics. Thanks.

[Barian Warlord]

I like them, they remind me of a rune archetype I'm working on.

[encapturer]

Thanks.

I purposely made them able to remove mana counters from anywhere on the field. I have no idea how a mirror match would turn out.

And a new Generator:

Spellweaver Bomb
Pyro/FIRE/Effect Level 1/300 ATK/300 DEF
When this card is destroyed by battle, place Mana counters on the monster that destroyed this card equal to the battle damage you took divided by 200, rounded up.
