Auriok Bladewarden + Freed from the Real Combos

Combo 1 with Mayael's Aria

Steps

1. At the beginning of your upkeep, Mayael's Aria triggers.
2. Holding priority, activate Auriok Bladewarden by tapping it, giving itself +X/+X until end of turn, where X is its power.
3. Activate Freed from the Real's second ability by paying {U}, untapping Auriok Bladewarden.
4. Repeat from step 2 until Auriok Bladewarden has power nineteen or greater, omitting step 3 on the final iteration.
5. Resolve the Mayael's Aria trigger from step 1, causing you to put a +1/+1 counter on each creature you control, gain 10 life and win the game.
