Ith, High Arcanist + Wake Thrasher

Ith, High Arcanist

Wake Thrasher

How it works

1. Declare Ith as an attacker.
2. Activate Ith by tapping it, untapping Ith and preventing all combat damage that would be dealt to or dealt by it this turn.
3. Wake Thrasher triggers, giving itself +1/+1 until end of turn.
4. Repeat from step 2.
