How it works

1. Activate Tidewater Minion's second ability by tapping it, targeting itself.
2. Ertha Jo's second ability triggers, copying Tidewater Minion's ability, targeting any other permanent.
3. Resolve both Tidewater Minion abilities, untapping it and the other targeted permanent
4. Repeat.
