At the moment:
Undead minion touches a pool and drains its power to become a Boss!!!
Monster or Boss corrupts a pool nothing happens
Although this makes it easier for us i don’t think its very fair for the zombies.
So my ideas:
Boss touches pool powers up its power. for example:
Lich/Lies/Jester/Coins Get more strength when people use cards/its ability
Corrupt/Timers Range of ability increases
Trailblazer reduce ability recharge
Monster touches pool:
Get a one time random burst of power copying a boss power
Teleporting dragons anyone?
