Whenever you cast an enchantment spell, if you don't control a creature named Keimi, create Keimi, a legendary 3/3 black and green Frog creature token with "Whenever you cast an enchantment spell, each opponent loses 1 life and you gain 1 life."
: Tatsunari and target Frog you control can't be blocked this turn except by creatures with flying or reach.
Cast enchantments to spawn Keimi, your engine token, then chain more enchantments to drain the table while building card advantage off enchantress effects. You can pivot to commander-damage beats by making Keimi or Tatsunari unblockable and loading up on auras/buffs, or grind opponents out with value enchantments and incremental drain. Most turns you're deploying cheap enchantments that each tick down life totals and refill your hand.
Free, repeatable drain via Keimi every time you cast an enchantment
Strong card advantage when paired with enchantress-style draw engines
Built-in evasion to push Keimi or Tatsunari as a Voltron beater
Sultai colors give access to ramp, removal, recursion, and counterspells
Resilient: many threats are enchantments that dodge creature-centric removal
Keimi is fragile and a magnet for removal; without it the drain stops
Enchantment removal and disenchant effects undercut the whole strategy
Slow to assemble engines compared to dedicated combo decks
Drain damage is incremental and can be outpaced by faster boards
Shields your enchantments and aura-loaded threats from targeted removal.
Add fast mana and enchantment tutors (Idyllic Tutor, Enlightened Tutor, Plea for Power) to assemble engines faster, and lean into ways to copy or recur enchantments. Protect Keimi with hexproof/indestructible enablers and consider Strionic Resonator or cost reducers like Herald of the Pantheon to push multiple triggers per turn. For the highest power, build toward an enchantment-fueled engine that can produce free spells (e.g., cheap enchantments plus draw) to loop drain triggers and close games quickly.
