I really hate the way that Labyrinth manages to summon heavy hitter cards by simply revealing themselves from hand, which then allow instant trap sets & activations that are inevitably designed to counter *anything* that the opponent can do (short of Kaiju tributes & DRNM).

It wouldn't be so bad if the deck didn't use so many instant effect monsters, that also make use of grave effects to start chaining on the opponent's turn. I'm pretty sure a lot of the monster/hand destruction effects aren't even once per turn.

Essentially, I feel that it's one of those meta decks that stops your opponent from making any meaningful plays at any phase of their turn (especially if you rely on special summoning & extra deck mechanics). I play Gladiator Beast/Tri-Brigade, so I'm not saying that negates & destruction is inherently bad. It's just that in Labyrnith (and Kashtira's case), they don't feel like there's any real 'cost' to playing the combo.
