Frenetic Efreet + Karplusan Minotaur + Safe Passage

Steps

1. Cast Safe Passage by paying {2}{W}, preventing all damage dealt to you and creatures you control this turn.
2. Activate Frenetic Efreet an arbitrarily large number of times by paying a total of {0}.
3. Resolve the first Frenetic Efreet ability, flipping a coin and either sacrificing Frenetic Efreet or causing it to phase out.
4. If you won the flip, Karplusan Minotaur's first ability triggers, dealing 1 damage to any target.
5. If you lost the flip, Karplusan Minotaur's second ability triggers, dealing 1 damage to any target of an opponent's choice.
6. If the opponent chooses you or a creature you control to be dealt damage, Safe Passage prevents that damage.
7. Resolve the next Frenetic Efreet ability, flipping a coin and not sacrificing Frenetic Efreet or causing it to phase out due to it no longer being on the battlefield.
8. Repeat from step 3.
