The Pikachu Illustrator card dates from a reader competition run in Japanese magazine CoroCoro Comic from 1997 to 1998

The calculator evaluates synergy across 14 strategic axes: Sacrifice sacrifice outlets + death trigger payoffs +1/+1 Counters counter sources + counter synergies (proliferate, doubling) Tokens token generators + creature count payoffs (convoke, Craterhoof effects) Landfall extra land plays/fetches + landfall triggers ETB/Blink flicker effects + enter-the-battlefield triggers Graveyard mill/discard/self-mill + graveyard recursion Creature Cheat reanimation/cheat effects + expensive creatures to cheat out Spellslinger instants/sorceries + cast-trigger payoffs Artifacts artifact density + artifact synergies (affinity, metalcraft) Enchantress enchantment density + enchantment triggers (constellation) Voltron equipment/aura count + equipped/enchanted creature payoffs Stax tax/denial pieces + asymmetric cost reduction Lifegain life gain sources + life gain triggers Wheels wheel effects + discard/draw triggers For each axis, the calculator counts enablers (the cards that set up the strategy) and payoffs (the cards that benefit from the strategy)
