Elegant Entourage

How it works

1. Cast Elegant Entourage by paying 3. It'll enter with a number of +1/+1 counters due to Arwen.
2. When Elegant Entourage enters, Watchful Radstag's evolve ability triggers, putting a +1/+1 counter on it.
3. Watchful Radstag's second ability triggers, creating a token copy of it. It'll enter with a number of +1/+1 counters due to Arwen.
4. When the token Watchful Radstag enters, the nontoken Watchful Radstag's evolve ability and Elegant Entourage trigger.
5. Resolve the Elegant Entourage trigger, giving Arwen +1/+1 until end of turn.
6. Resolve the Watchful Radstag trigger, putting a +1/+1 counter on it.
7. Repeat from step 3.
