I wonder why did they release a card so broken. The restriction on Dustons is really insane, over the top. Putting 3 of these guys on the opponent's board is a guaranteed field lock. There are very very few cards that remove a Duston from your field by summoning a monster.
Yeah. I'm worried even without House Duston... that would just break the game entirely. I don't "feel" for Duston players that their entire precious degenerate stall burn deck got killed by link summoning. I don't want them to have their good time here again.
Stall is degen everywhere. And while that spell and House Duston are the broken easy way of putting them on opponent's board, they aren't the only way, as cards like "Give and Take" exist. So they aren't "box filler", they're hardcore stall burn support.
