To comment on the actual card itself, I have to ask what exactly the effect accomplishes. Flooding is a card exists that already exists in the game. This card deals effectively infinite damage to the outer edges every turn, far more damage, for a much cheaper cost and much cheaper upkeep, and much less vulnerable because Flooding is not a expensive 2 HP creature but is instead a permanent.
And flooding is from what I've seen widely considered UP. Flooding does have very specific restrictions that let a couple things get through on the far side of a blue moon, but by and large this isn't why it is considered UP.
tl;dr: If flooding is superior to this card in nearly every way, and flooding is considered massively UP, what does that say of how effective this card would be?
