Blacephalon UNB: EvenSlightly Favored I honestly feel like this matchup is pretty favored for us, but Im unsure if my experience is an accurate representation of the matchup
C Common Tri-Brigade Arms Mouser X EARTH Link 2 [ BeastLinkEffect ] ATK 1800 DEF - 2 Beast, Beast-Warrior, and/or Winged Beast monsters If this card is Link Summoned: You can send 2 "Tri-Brigade" cards with different names from your Deck and/or Extra Deck to the GY, except "Tri-Brigade Arms Mouser", also you cannot Special Summon from the Extra Deck for the rest of this turn, except Beast, Beast-Warrior, or Winged Beast monsters
What I like about Kelsien, the Plague is that they dont force much direction outside of being one of your better options for a pinger deck
