I came up with this combo involving the new card, Myriad Construct and Ground Rift (or any storm/replicate card). Due to some bizarre rule interactions, we can storm off turn 1 and create 24 1/1 tokens.
At this point, two triggers go on the stack at the same time, the storm and the sacrifice triggers. As the controller, you get to choose the order, so put storm trigger on top.
Stack: Top>SXG>Bottom (where S is storm trigger, X is sacrifice trigger, G is Ground Rift)
Storm resolves creating 4 copies which go on the stack and trigger 4 more sacrifices. Put in arbitrary order.
Once we've put the triggers on the stack, it doesn't matter that the Ground Rifts fizzle because all the sacrifices are already on the stack and they don't target, so they don't fizzle (rule 608.2b) and resolve as much as posssible (609.3).
Furthermore, the tokens will be created using the last known power of Myriad, even if it no longer exists (413.2f).
So in the end, we get a number of tokens equal to four times our storm count.
I like it and also think the concept is due to some obscure and honestly unintuitive rules. That said maybe going for the traditional storm build with this slotted in could work better. That way you don't go down to 1 win con. You still have grapeshot and warrens but 1 or 2 of these to also help in matches where shot isn't the best card for the job.
I see you have kinda done that already, but maybe instead of playing Val you could play Boral or electromancer? I don't think you have to lose the package of Gifts and the flashback card to add in this new card.
Thanks! Those are good thoughts, but I have no idea how we would work Myriad into the Gifts storm build.
Gifts storm wants rituals, a mana reducer, a Gifts Ungiven in hand; and 2+ Past in Flames and 2+ storm cards in deck. Myriad storm wants rituals and a storm/replicate card in hand. So pretty much the only overlap would be rituals.
Playing Gifts, we already win deterministically with our choice of Empty the Warrens or Grapeshot, so there's no reason to add Myriad, which does the same as Empty but is more susceptible to counterspells and removal. And Baral/Electromancer are "strictly" worse than extra rituals/Simian Spirit Guide/Wild Cantor with Myriad/Empty because we only need 4 or 5 mana to go off, so they never reduce the number of cards to combo, can't go off turn 1/2, and reduce our storm count.
The main advantages Myriad has over Gifts storm is removing the tutor package, resisting kill spells, not needing the grave, and being more synergistic with Empty the Warrens, Aria of Flame, and cheating in things like Chandra and Blood Moon. These are incompatible with playing the Gifts package. Meanwhile, Gifts is more consistent because with enough mana, Gifts can win the game alone, and because they play more cantrips.
I wonder if the addition of 2-3 Gut Shots would be valuable.
The most common way to interact with this combo would be to target Myriad, before the storm/replicate trigger resolves. This would fizzle the copies, leaving us with only 8 tokens (the trigger from our initial storm spell + their spell). 8 tokens isn't enough to win through 2 blockers. But if we respond with a Gut Shot, this creates 12 tokens, which wins through virtually any number of blockers played on curve.
Plus Gut Shot is always just good for upping our storm count and bolting the bird.
I can see that. I wonder if lava dart may also be useful in here? If you want to lava dart the bird or go face you could easily sac a mountain for 4 more tokens at the end of the combo turn.
My plan is to play it with Lightning Greaves, Leonin Shikari, and Outrider En-Kor to get infinite triggers. While none of the cards themselves are that good. I'm aiming for the synergy is greater than the sum of all the parts. Plus Greaves are just good at protecting whatever else you plan to put in the deck. While also protecting the enablers.
I just realized something. You probably need some way to give the tokens haste. I don't know how much Mana you typically generate per go off turn, but maybe either one of the bushwackers could work or you could go with Hammer of Purphoros to be cast the previous turn. Or on the combo turn there is Mass Hysteria to up the storm count.
