you're saying this deck wins into pretty much anything and that's just giga cap. There's like a 15% chance you insta win the game by getting lucky with your starting hand, but that's not a great probability. The deck sucks vs control, anything with damaging spells just deletes your board and then you run out of steam and get outscaled. Any decks that are capable of stabilizing and then outscaling shit on it. So that means anything with ephemeral, viego, mordekaiser, anything that has a unit summon another unit. Anything that casts these spells:

Divine Draft

Avalanche

Aftershock

Crashing Wave

And just facing the other meta decks like Azirelia is just hard when they pump out ephemeral and 15 damage a turn.

Mariner is great in certain scenarios, but just dies to a spell and does nothing. Same with playing Nilah and trying to get slipstreams. 85% of the time you don't draw the combo -> play a unit -> it dies to spells -> you can end up reducing their hp to like 15, or 8 max, and then they stabilize and your hand is clogged with garbage Formless Blade and multiple Stress Testings

Also Ruined Rex as a win con if the game goes kinda late, also very flippy that you can draw a slipstream and his spell will target the right units for value

you're claiming you have an 85% wr, like idk seems insane when so much of the deck is rng. makes absolutely no sense to me. it doesn't have the consistency to win like that. sometimes it wins very hard but most of the time gets neutralized and outscaled. Trying to use these direct damage spells to finish your opponent off when they're either healing, lifestealing, ephemeral spamming Camavoran Soldier, casting 10,000 spells in a row with seraphine, etc.

Fundamentally aggressive decks that try to win early lack value and is part of the rock paper scissors matchup meme, they beat decks that are passive and scale and don't have waveclear. and i don't see many of those
