The Tenth Doctor + Mana Echoes + Reality Strobe + Third Path Iconoclast

The Tenth Doctor

Mana Echoes

Reality Strobe

Third Path Iconoclast

How it works

1. Activate The Tenth Doctor by paying 7, removing all time counters from Reality Strobe.
2. Reality Strobe triggers, causing you to cast it from exile without paying its mana cost.
3. Third Path Iconoclast triggers, creating a creature token.
4. When the creature token enters, Mana Echoes triggers, adding C for each creature you control that shares a creature type with the token.
5. Resolve Reality Strobe.
6. Repeat.

This loop centers around The Tenth Doctor's costly time-travel ability, which rapidly strips time counters away from suspended spells to cast them for free. When you accelerate Reality Strobe out of exile this way, casting it triggers Third Path Iconoclast to flood the board with Soldier tokens. Those new bodies immediately supercharge Mana Echoes, generating a massive windfall of colorless mana to pay for the Doctor's next activation. As Reality Strobe resolves, it bounces an opponent's permanent and exiles itself right back onto the suspended queue with three new time counters, ready to be immediately ripped out of exile again and perpetuate the storm.
