The Tenth Doctor + Taigam, Master Opportunist + Beacon of Tomorrows

The Tenth Doctor

Taigam, Master Opportunist

Beacon of Tomorrows

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 Beacon of Tomorrows by paying its mana cost.
3. Taigam triggers, copying Beacon of Tomorrows and then exiling it with four time counters on it and giving it suspend.
4. Resolve the copy of Beacon of Tomorrows, causing you to take an extra turn after this one.
5. Move to your next turn. At the beginning of that turn's upkeep, Beacon of Tomorrows 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 Beacon of Tomorrows 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 Beacon of Tomorrows's suspend trigger, causing you to cast it from exile without paying its mana cost.
9. Repeat from step 3.
