Tonight’s twitter has graced us with the LIGHT Eidolon Fusion!
Shoukanjuu Merkabah / Merkabah the Eidolon Beast
Light Machine / Fusion / Effect
“Aleister the Eidolon Summoner” + 1 LIGHT monster
(1) Once per turn, during either player’s turn, when a monster effect, or Spell/Trap Card is activated: You can send 1 card of the same card type (monster, Spell, or Trap) from your hand to the Graveyard; negate that activation, and if you do banish it.
As a note, the name refers to Merkabah Mysticism, yet more Jewish references!
