Decks from the first two-thirds of Time Spiral block, in the extended.

Red Clock
Concept:
Fast mono-red with creatures and burn. I’m trying to develop “fast clock” decks to test other decks against, using in-block components. This deck follows the standard practice of trying to put creatures out relatively early, then using burn to clear the way and finally take out the opponent. The Reiterates can come in against other burn or against counterspells (in the former case, it creates the danger of draws, which might slow the opponent down). It’s much slower than a Standard R/G zoo deck.

Black Clock
Concept:
Once again, a fast clock attempt, this time in black. Time Spiral black is good as a clock color based on efficient and unblockable critters. This deck doesn’t drop anything until turn two, but from then on, it can pour out little, potentially hard-to-block creatures. The Blooms can, at best, allow a turn-four Overseer, as well as accelerating a crippling Phthisis or Temporal Extortion.
