The Tenth Doctor + Taigam, Master Opportunist + Rise of the Eldrazi

The Tenth Doctor

Taigam, Master Opportunist

Rise of the Eldrazi

How it works

1. Cast the self-suspending card by paying its mana cost if its in your hand, or any other spell otherwise if you have not cast a spell this turn.
2. Cast Rise of the Eldrazi by paying its mana cost.
3. Taigam triggers, copying Rise of the Eldrazi and then exiling it with four time counters on it and giving it suspend.
4. Resolve the copy of Rise of the Eldrazi, causing you to take an extra turn after this one.
5. Move to your next turn. At the beginning of that turn's upkeep, Rise of the Eldrazi and the self-suspending card's suspend abilities trigger, removing a time counter from each of them.
6. Activate The Tenth Doctor by paying 7, removing three time counters from Rise of the Eldrazi and the self-suspending card, triggering their suspend abilities.
7. Resolve the self-suspending card's suspend trigger, causing you to cast it from exile without paying its mana cost, and eventually exile it with time counters on it.
8. Resolve the Rise of the Eldrazi's suspend trigger, causing you to cast it from exile without paying its mana cost.
9. Repeat from step 3.
