But I play novice tournaments when I am in diamond yet I still get beat :( There is a small flaw in that plan though, since bots play so much, why can't they just keep surrendering their way down to gold, join the tournament, then go back up? Or what about just creating more low level accounts and delegating OP cards to them? I feel like that is just going to hurt normal players.

I sometimes get beta legendarie'd there too. Bots can theoretically drop bellow dia, but that's very costly for them. Maybe even more than 2k DEC for th-12s (+ it might still cost like 150 instead of 3 or 10 to enter novice tourney as gold) Same for delegations, they can, but it will put cards on cd... Making it net loss for bots is as good as banning them :)

True but the cooldown on tournaments has not come into effect yet. And remember, they can create new accounts and buy new cards solely for farming tournaments.
