I tried the new Hela deck as soon as hell cow got the change. Within like a few matches, I took giganto out and put red hulk in. Kept finding people not playing a card the first couple rounds and arishem decks not spending all their energy. My red hulk was getting way above giganto and getting hit by hell cow then brought back.
Any card on the board can only activate one time, no matter if it’s bounced or replayed somehow. You activate symbiote to join him and he is considered activated for the rest of the game, he doesn’t get a new activate when he joins
