Elixir of Immortality seems out of place there.

keep the fish and take out something else for the horror.

i'd recommend swapping Scalding Tarn for Verdant Catacombs and adding some more snow basics. for the removal i think Fatal Push and Counterspell are the best in these colors. Harbinger of the Seas counteracts your own dual lands and makes them only able to tap for blue.

6 mana is gonna be really hard to hit with only 20 lands and no ramp.

whats the line of play to build a storm count of 19 for grapeshot? would it not be easier to build a count of 3 for Dragonstorm?

kamarupa: Quickchange

i've had my own "x-cost" deck ever since Unbound Flourishing was released. i've posted it on here if you wanna take a look at it for inspiration.

how would it be 15? without a way to give it indestructible, you'd only get 5 before the dino dies.

you'll want to cut down to 60 cards, and add removal.

Sol Ring isn't modern legal. for the lands, you probably want some Wooded Foothills and Stomping Ground

i was thinking Temur Battle Rage and Claim / Fame. Wrenn and Six to replay your fetch lands. if you decide against red, Dismember and Grim Tutor could be useful.

Unbound Flourishing. the tron lands don't really fit in this deck. you wouldn't be able to get the tron lands online plus a rosheen on field until turn 5. it'd be better to use things like Arbor Elf and Utopia Sprawl to ramp.

are you against adding red?

for the red dredge deck, it's not even "support", it's just some dual lands, and that's not gonna reduce consistency. and yeah i figured red dredge would be mono red. but if i just search "pauper dredge", literally none of what i find is mono red. dredge in any form doesn't appear on mtggoldfish, but even when i google it the only way to find mono red is to search for it specifically. otherwise it's just all jund lists. getting 20 creatures into the deck with Stinkweed Imp alone is going to take too many turns. by then, other decks have already won, or gained too much life, or played enough removal that you can't flash back the Dread Return.

this is why other dredge lists have lands that can produce black mana, and additional ways of getting creatures into play.

have you actually tested this? you're being awful condescending about a combo that isn't winning you the game. it's unlikely the giant deals 20 damage with it's etb all at once, and i just don't see you being able to sacrifice 6 total creatures to Dread Return it a 2nd time. all i'm suggesting is that you add some dual lands.

yeah i knew all that, but you should still be able to hard cast those cards. trying to draw 3 cards in a turn for a Sneaky Snacker just to sacrifice it and 2 other creatures to Dread Return a Lotleth Giant is a lot of investment for not a lot of return.

you need more than just mountains when your cards cost blue and black.

in modern, 6 mana is too expensive for a card that doesn't win you the game on the spot. the best removal in these colors is gonna be Lightning Bolt, Fatal Push, and Terminate. modern is too brutal a format to have a final fantasy theme just for the sake of it.

you'll want good removal like Abrupt Decay or Assassin's Trophy. probably trade the swindler for Badgermole Cub. marsh, glade, and wastes can be traded for basic lands. they'll etb tapped at inopportune times and the life loss isn't worth it.
