tenyi yugioh deck Swordsoul You can Special Summon this card from your hand Monk of the Tenyi -

These include two unique Ritual Summons, a variant of the Red-Eyes reliant on a Trap Card, and a Fusion Monster which looks nothing like its constituent parts

This one works best with low mana value Commanders, and makes running blink cards like Ephemerate and Eerie Interlude that much better

This rarity is similar as the previous Prismatic Secret Parallel Rare from the OCG, but with a rainbow/mirror-like silver name like a regular Secret Rare instead of the shattered silver name like a Prismatic Secret Rare

That kind of trade-off is usually worth it, especially since Ketramose is hard to remove and comes with menace and lifelink to help stabilize once its ready to attack
