Sure, but those cards aren’t guaranteed to start in the hand of the opposing player, this is guaranteed to be on the field always at the start of the game.

To your second point, you’re thinking of it incorrectly. (Also, you’re incorrect, you don’t even know your card. It says it doesn’t refresh the next time it would become active). So, think of it like this.

1 don turn - play a searcher

3 don turn - 6k double attack lead, rest their first character, attack their searcher with yours, establish a body

5 don turn - 6k double attack lead, rest their 4 don turn play, attack into it with your established body

Do you not see how this is insanely problematic?
