I feel like the main problem is the PSTC, but that's why I'm posting in the first place. To get feedback.

If Special Summoned this way, you can add 1 "Froggy Fighting Force", "Froggy Forcefield", or "Froggy Flow" to your hand. You can only activate this effect of "Sludge Frog" once per turn. An Xyz Monster that was Summoned using this card as Xyz Material gains this effect:

Froggy Fighting Force
Continous Spell

If you control a "Frog" monster, Spell/Trap cards you control cannot be targeted by card effects. Every Aqua monster you control gains 300 ATK for each Aqua monster you control. When a "Frog" monster you control declares an attack, return 1 card your opponent controls to their hand. If this card is sent to the GY because of an opponent's card effect, draw 1 card.

 

Froggy Flow
Continuous Spell

When this card is activated, add 1 "Frog" monster from your Deck to your hand. If that "Frog" monster was a Level 2/Aqua/WATER monster, you can send 1 "Frog" monster from your Deck to the GY. If a "Frog" monster you control would be sent to the GY because of an opponent's card effect, you can banish 1 "Frog" monster from your GY instead. You can only activate each effect of "Froggy Flow" once per turn.
