At the beginning of your end step, if creatures you control have total toughness 10 or greater, draw a card. Then if creatures you control have total toughness 20 or greater, untap each creature you control. Then if creatures you control have total toughness 40 or greater, each opponent loses half their life, rounded up.
Betor is an Abzan toughness-matters commander that rewards you for fielding fat, high-toughness creatures and wide token boards. Build up total toughness across thresholds (10/20/40) to draw cards every turn, untap your team for pseudo-vigilance and big mana, and ultimately blast every opponent for half their life each end step. You stall the early game with defenders and ramp, then snowball a board that converts toughness into card advantage and lethal life loss.
End-step half-life loss scales to multiple opponents and ends games regardless of life totals once you hit 40 toughness
Built-in card draw and untap make the board engine self-sustaining and reward going wide or tall
Abzan colors give access to the best ramp, removal, lifegain, and token producers
High-toughness defensive creatures naturally fortify you against early aggression
Untap effect enables repeatable tap abilities, big mana, and infinite-style combos
Toughness thresholds collapse to a board wipe, leaving you with little payoff and overcommitted
Slow to come online without ramp or early board presence
Five mana and reliant on creatures, so the deck is vulnerable to Wrath effects and graveyard hate
High-toughness creatures often lack evasion or punch outside the commander's ability
Telegraphs the win, drawing removal and combat aimed at Betor or your wide board
