When this card is discarded from your hand by an opponent's card effect, Special Summon up to 2 Level 4 or lower "Dark World" monsters from your Graveyard. If this card is Tribute Summoned by offering at least 1 "Dark World" monster as a Tribute, this card gains the following effect: • The effects of all Spell and Trap cards your opponent activates become "Randomly discard 1 card from your opponent's hand".

Level 2
200/1200
If this card is used as a Tribute for the Tribute Summon of a "Dark World" monster, you can discard 1 card from your hand to the Graveyard. If you do, this card can be treated as 2 Tributes for the Tribute Summon. During your End Phase, if 2 or more cards were discarded from your hand during this turn, you can remove this card in your Graveyard from play and draw 1 card.

Well, Chrimson can be considered well overpowered when combined with a Dark World Deck, but considering that it's a random card that's discarded. and obviously not all cards in a DW deck are going to activate their effects when discarded, it's not too bad.

I think Ma-Rune's second effect should be written along the lines of "During the End Phase of a turn you have discarded 2 or more cards from your hand due to card effect(s), you may remove from play this card in your Graveyard to draw 1 card." But I suppose the way you've written it could also work.
