Anti-supports all Duel Terminal Link archetypes (so World Legacy, World Chalice, Troymare, Krawler, Mekk-Knight...)
Just so you know, those are not confirmed to be related to the Duel Terminal storyline yet.
World Legacy - World Arm
Link Markers: bottom-left, bottom-right
2 "World Legacy" monsters, including "World Legacy - World Chalice"
This card gains the effects of the materials used for its Link Summon, also its original ATK becomes equal to the total ATK or DEF (whichever is higher) of its Link Materials. You do not have to Tribute monsters to activate the effects of "World Legacy" cards. If this card is Link Summoned: Set 1 "World Legacy" Quick-Play Spell or Trap from your Deck or GY. That Set card can be activated during this turn. If a "World Chalice", "Krawler", "Mekk-Knight" or "Troymare" Link Monster, or a "World Legacy" monster, is Summoned on your opponent's side of the field: You can negate that monster's effect, also you can take control of it.
Flavor and stuff:
It's named Arm because basically is a Link pseudo-Fusion of World Chalice and any of the available weapons, so it's just the weapon of choice being operated by the core, a single "living" arm.
2 Reptile, Dinosaur and/or Dragon monsters
