Well that was quick.
We can see the new Starter Deck, plus Decode Talker being the confirmed TCG name of Yusaku’s monster, as well as Cyverse being the confirmed name for the new Type. The Extra Monster Zone and Main Monster Zones also retain their OCG names.
We can also see that the way TCG handles Link Materials is by writing the Link Number on the Material Line again, while using the word “min” to denote you need at least that many to Summon them. The official terminology of the connection between a Link Monster and the monster its Link Markers are pointing at is also confirmed to be “link”.
