Why is this OP?
because of the cards posted
makes the costless, producing creatures too powerful
and makes the Hope fuel resistant to rain of fire, Lstorm, etc. at the same time it's increasing its offensive power
SoP does this so much better.
Agreed - SoP does a LOT of things really well but is a rare card/shard. Along that reasoning it can also replace current in-game cards Blessing, Plate Armor, Chaos Power, Rage Pot/Elix (to an extent), Accel/OD (to an extent), Adrena/Epi (to an extent), Shard of Wisdome (to an extent), Nightfall/Eclipse (to an extent), and Shard of Freedom (to an extent). Might even be a few more I am forgetting right now. However, similar cards are OK so long as it isn't too similar and isn't in-element similar (as I understand current card design to be recommended).
