I voted 20 Overflow because:
1. It's my entry. (Thanks those who have voted my entry for your support)
2. I can't say mine is perfect, but every other card has something that stops me from voting them
5, 9, 11: I don't have to explain myself (0 vote)
1: Chain 6 = Ultimate invincibility for 12 turns
2: That would use 1 more variable = more lagging. And OP 'cuz you can reduce the cost of a skill to
by just casting it once. Examples which this would be obviously OP: Alchemy cards, Fractal
3: Just giving water a bigger difference in terms of poison removal. I would vote this if it were not water

10: Nice, but doesn't match with Flooding. You have to think of how an idea interact with the current/developing cards
12: Bolt rush gets OP
13: Double damage of the whole field is OP, even only 1 turn
14: A plague generator is OP

17: Too complicated
18: See 2, and think of EPD
19: We have Ice Shield
21: See 13
22: Giving dive to creatures has been discussed many times and the conclusion is OP if casted on dragons, and you are giving it to EVERY creature?
23: See 7
