I'm curious as to how the Copy abilities would interact. It depends on how the game is programed. For the purpose of demonstrating my thoughts, I will use Saki
and an imaginary card. Imaginary card stats: 7/3 A: Copy: Opp Ability and B: Copy: Opp Bonus.
Hypothesis 1: Copied but useless.
Imagine attempts to copy Saki's ability, but it doesn't get an effect from it. Saki
attempts to copy Imagine's bonus, but she doesn't get an effect from it. Imagine successfully copies Saki's bonus and both cards lose 2 power.
Hypothesis 2: Copied as stated.
Imagine copies Saki's ability which is then used to copy her bonus. Saki
attempts to copy Imagine's bonus, but it tells her to copy it again (infinite loop), therefore Saki's ability becomes useless. Imagine copies Saki's bonus without issue. This means that Saki
loses 4 power and Imagine loses 2.
Hypothesis 3: Copy what it's copying.
Imagine copies Saki's ability which is copying Imagine's bonus which is copying Saki's bonus of -2 power. This means that both cards lose 4 power. This is the interaction I'd prefer.
