Elegant Entourage + Hapatra, Vizier of Poisons + Devoted Druid

Elegant Entourage

Hapatra, Vizier of Poisons

Devoted Druid

How it works

1. Activate Devoted Druid's first ability by tapping it.
2. Activate Devoted Druid's second ability by putting a -1/-1 counter on it.
3. Hapatra triggers, creating a creature token.
4. When the creature token enters, Elegant Entourage triggers, giving Devoted Druid +1/+1 until end of turn.
5. Resolve the Devoted Druid ability from step 2, untapping it.
6. Repeat.
