You want to add more forms of poison but did not consider letting purify remove them.
Note: Purify is a rather poor design for an answer to poison. If your goal with this card is to add an additional answer to "status damage" then you might want to consider addressing why purify is a poor design.
Aka make it useful even when nobody plays "status damage" decks AND make "status damage" decks still have a chance of winning vs it.
When nobody plays "status damage" decks, it can prevent spell damage i.e. blocks Psion/SoW directly, also counters Bolt decks.
In my proposed new types of status damage, they are like a supplement to a strategy e.g. Fire damage is only inflicted when Fallen Angel is dead and ES cause weak damage with a chance to inflict Silence. Therefore there shouldn't exist a pure "status damage" deck.
Maybe it should only work on the target creature
Have this also remove Adrenaline and Gravity Pull as well? It does say status.
What about the addition of removing Freeze and Delay? Yes, there is no real thematic connection, but it does expand its uses.
So maybe this can work on a creature too? If that is the case, will it be OP when compared to RT?
