Sundial of the Infinite + Elite Arcanist + Chance for Glory

Sundial of the Infinite

Elite Arcanist

Chance for Glory

How it works

1. Activate Elite Arcanist by paying 3 and tapping it, casting a copy of Chance for Glory without paying its mana cost.
2. Resolve the Chance for Glory copy, giving creatures you control indestructible, taking an extra turn after this one, and creating a delayed triggered ability.
3. At the beginning of your end step, if this is an extra turn from Chance for Glory, its delayed triggered ability triggers.
4. In response, activate Sundial of the Infinite by paying 1 and tapping it, ending the turn and exiling the triggered ability.
5. Repeat each turn.
