Triskaidekaphobia wins the game on your upkeep if any opponent has exactly 13 life — and Tree of Perdition exists specifically to put someone there. Four mana for a do-nothing enchantment is a real cost, but the combo with Tree is cheap enough and obscure enough to catch tables off guard.

Commander is where Triskaidekaphobia actually lives. With 40 starting life, opponents need to be significantly damaged first, which makes it a two-card kill rather than a standalone threat — but Tree of Perdition handles that setup cleanly, and the enchantment's symmetry clause (giving opponents the win too) rarely matters when you control the life-total manipulation. In Legacy, Modern, and Pioneer it's a novelty at best; faster formats don't give you the time to set up a four-mana enchantment that wins on a future upkeep, and dedicated life-total strategies have more reliable lines. Oathbreaker can replicate the Commander experience if your signature spell interacts with life totals.

Price Context
Current price
$0.33 bulk tier
At $0.33, Triskaidekaphobia is firmly bulk — the kind of card you pick up as a throw-in. Demand is narrow enough that the price is unlikely to move unless Tree of Perdition spikes and drags it up as the mandatory companion.
