Appa, Steadfast Guardian + Restoration Angel + Semblance Anvil

Appa, Steadfast Guardian

Restoration Angel

Semblance Anvil

How it works

1. Cast Appa either from your hand or from the command zone by paying plus commander tax, if applicable.
2. When Appa enters, its first ability triggers, exiling Restoration Angel with the ability to cast it later from exile.
3. Cast Restoration Angel from exile by paying 0.
4. Appa's second ability triggers, creating a 1/1 Ally creature token.
5. When Restoration Angel enters, it triggers, blinking Appa.
6. Repeat from step 2.

This elegant loop relies on Appa, Steadfast Guardian to banish Restoration Angel into exile with its airbend ability, granting it a reduced cost that drops to zero when paired with the artifact Semblance Anvil. Once you cast the Angel for free from exile, its entry triggers a blink on Appa, which in turn resets the cycle and triggers Appa's secondary ability to flood the board with 1/1 white Ally creature tokens. Every iteration of this bouncing dance feeds your storm count and repeats the enters-the-battlefield and leaves-the-battlefield triggers indefinitely.
