Whenever Calamity attacks while saddled, choose a nonlegendary creature that saddled it this turn and create a tapped and attacking token that's a copy of it. Sacrifice that token at the beginning of the next end step. Repeat this process once.
Saddle 1
Saddle Calamity for just 1 with a nonlegendary creature, swing in with haste, and copy that saddler twice as tapped attacking tokens to double up combat damage and ETB triggers before sacrificing them at end of turn. Build around fat token-makers, big attackers, and creatures with juicy enter-the-battlefield or attack triggers so the two free copies snowball board presence or burn each turn.
Saddle 1 is trivially cheap, so you almost always get both copies on Calamity's attack
Two free tapped-and-attacking copies effectively triple a single creature's combat damage and ETB value every turn
Mono-red gives consistent ramp, rituals, and access to powerful nonlegendary beaters and token engines
Token copies enter attacking, dodging summoning sickness and removal timing
Snowballs fast — one good attack can end the game out of nowhere
Mono-red lacks card draw and recovery, so a board wipe or removal on Calamity stalls hard
Reliant on connecting in combat; getting chump-blocked or fogged neutralizes the engine
Tokens are sacrificed at end step, so the value is fleeting unless you blink/keep them
Wants a creature already on board to saddle, making empty boards awkward
No protection or evasion built in — Calamity dies to most spot removal
Legendary Creature — Horse Mount
