Barian Battlemorph! Galaxy-Eyes (Skill Card) (100%)




Barian Battlemorph! Galaxy-Eyes (Skill Card)
ATK:

DEF:
0
You can use this Skill's second and third effects once per turn if your Extra Deck contains 2 different "Number 107" Xyz Monsters. 1: At the beginning of the Duel, all "Rank-Up-Magic - The Seventh One" cards in your Deck are placed at the bottom of the Deck. During your turn, you can only Normal Summon or Special Summon Level 4 or 8 LIGHT or DARK Dragon monsters and Xyz Monsters. 2: Reveal 1 Level 8 Dragon monster or 1 "Tachyon" monster from your hand. Add 1 Level 4 or 8 LIGHT or DARK Dragon monster from your Deck to your hand. 3: Can be used before your normal draw. Barian Battlemorph! Regain your true form! One of the cards from your normal draw this turn will be "Rank-Up-Magic - The Seventh One" from your Deck.
Barian Battlemorph! Galaxy-Eyes acts as the "heart" of the Tachyon deck's entire strategy, with two extremely powerful effects that ensure both stability and finishing potential:
Right on your first turn, you are allowed to reveal one "Tachyon" card or one Tier 8 Dragon monster from your hand to directly summon Schwarzschild Infinity Dragon ( you can also summon additional Light or Dark-type Dragon monsters such as Levianeer to clear the board, or Starliege Seyfert , Nebula Dragon to further expand your combo ). This creates absolute stability, making it easy for you to execute a one-card combo to summon Tier 8 Xyz Boss monsters along with your Trap cards.
Draw Sense Ultimate (Going Second / Next Turn): On your next turn (or even on your first turn if you go second), this skill allows you to transform into Barian and ensures your draw is definitely the Rank-Up-Magic Spell Card - The Seventh One . This is the core "turnaround" card to directly summon Neo Galaxy-Eyes Tachyon Dragon , nullifying the entire board and preventing your opponent from activating any effects.
Thanks to this skill, Tachyon can easily play through interruptions (like Effect Veiler) and always has ample resources available to overwhelm opponents in subsequent turns.
