Undertale OST - NGAHHH! Extended
0:00 - 0:05
Undyne is a great and versatile monster that can fit into any deck, barring only the extremely aggressive. Her unique ability to split a large amount of damage 1 at a time is ensures she is equally capable of dealing with either a few small monsters or a single big target. The split also counters Dodge monsters, as each hit is counted separately.
Undyne's second ability to summon a Spear also provides great stats, and it is not uncommon to use Undyne on a completely empty board to develop two very big threats comparable to Angel of Death. This makes her one of the most versatile cards in the game, able to have both defensive utility and offensive pressure.
Undyne is also one of the very few Royal Guards that can immediately react to enemy monsters with more than 4 HP. This makes her an incredibly valuable card in the Royal Guard deck.
Counters[]
Monsters like Mad Dummy cannot be killed by Undyne's ability as it distributes the attack 1 damage at a time upon the monsters. As such, Armor monsters block her effect entirely.
The Spear from her second ability is summoned with base stats, which means Silence will not affect it. However cards like Queen and Seam can be used to reset a bigger Spear, because if it gets released, it will go back to its 3/3 form.
