you have too many lands that don't produce colored mana, and too many that enter tapped. you'll be solidly mid game before you even start casting spells, and your only removal is a MV 3 card that only gets rid of the weakest threats. Doppelgang is far too expensive for what it does. even for an X value of 2, you need 8 mana and are only getting 4 damage out of it. the concept just looks too clunky. if you really want to use Doppelgang, i'd really recommend using better lands and copying good creatures instead of lands. Pawpatch Recruit would be a good one to copy.

you got 120 cards in there.

what format are you trying to make it for? says standard, but most of this isn't standard legal.

legendofa he's asking if Grasp of Fate can exile the forge.

Sarkhan the Bloodthirsty

legendary creature- human berserker shaman

first strike, trample

when a dragon enters the battlefield under your control, you may draw 1 card and have it deal damage equal to it's power divided as you choose among any number of targets.

4/4

Bahamut, Father of Dragons

legendary creature - dragon god

flying, trample, first strike, vigilance.

dragons you control have haste.

whenever bahamut enters, attacks, or blocks, choose one.

-target dragon you control fights target creature you don't control.

-target dragon you control gains protection from the color of your choice until end of turn.

-deal X damage to target player or planeswalker, where X is the highest power among dragons you control.

7/7

BotaNickill but what about...16 racks?

Andramalech: i'd wanted a return to kamigawa ever since return to ravnica, when i first realized wotc could/would revisit old planes. for years i had to listen to people say "it'll never happen because kamigawa was a dud block". shame we couldn't get playable samurai though.

CNG_Stream brazen borrower is like $3 lol

since nothing costs more than 3, you could cut some or all of the mana ramp for removal. Chord of Calling could be swapped for Green Sun's Zenith so long as your white/red creatures are also green.

Balaam__ you can still sac a creature with shroud, but it will only count as 1 of the 3 creatures you need to sac for Behemoth's Herald. sacrificing a multicolored creatured won't count for the multiple color requirements in Behemoth's Herald

you don't have any turn 1 or 2 plays, and not enough lands to play anything MV4 or higher.

with only 19 lands, you won't have enough to cast anything over MV 3 reliably. i'd recommend putting in another land and cutting anything MV4 or higher.

FormOverFunction: those cards aren't modern legal, and i think you were thinking of a different card when you mentioned Paralyze.

Cloudy2024 the worst matchups have always been the midrange decks. with decent draws i'm winning on turn 4

i'd just change the shell to make it noncombo. there are other cards besides sorin that can damage the opponent when you gain life, and other ways of gaining life that won't cost you cards in hand. things like Weather the Storm or Lightning Helix. "soul sister" effects could also work.

Cloudy2024 i've been playing slivers in tournaments since before MH1. it used to have Striking Sliver, but i took it out.

i think there are more reliable ways to win with lifegain. this build seems inconsistent with too many cards that work against each other.

in scryfall i searched modern legal cards with the exact text "becomes a creature" and there were 2 results, neither of which do what you're looking for.

i don't think there's any cards that trigger from a card changing it's type, but you can check scryfall. the space in the deck would be pretty limited anyway. with vehicles, you're already running an above-average number of "creatures", then you need room for removal.

PolyTheCakeEater: i've been playing slivers since before MH1. there's only space for 1 rainbow land, because rainbow lands don't provide the colors i need for the non-sliver spells, and don't count as a swamp for Sedge Sliver. sliver hive will be replaced by Cavern of Souls when i can afford them. other than that i rarely have problems getting the colors i need. 24 lands is what i need for Collected Company. i've tested the deck with 20 and 22 lands, and it wasn't enough. manaweft allows for early coco's, and i do have a haste enabler. dregscape and leeching would make the deck slower since i'd have to take out lords to make room. i used to use diffusion, but it got replaced by lavabelly.
