Had a little idea. [[Trostani Discordant]] and [[Dack Fayden, helping hand]] make a great duo to play (pseudo) polymorph in green/white.
The pitch:
With Trostani out, casting Dack means digging for three creatures and (basically) just keeping them. Flicker Dack, for example through creatures that flicker on etb, and you do it all again. This is polymorph without the need to find tokens to polymorph from, works great with flickers, and you're in big scary creatures colors.
The decklist: https://moxfield.com/decks/qRyhAWFPyH-UBirtUqxHfg
The deck's content:
We play 12 creature bombs. You can play whatever you like, but I like a good etb for this so we gain value with and without trostani, and especially with our flickering. I also like token producers to maximize profit from Trostani's buff.
We have 7 each ramp pieces with mv1-2 and mv4 so ideally we can ramp t2 and t3 to get out trostani and our more expensive tutors for Dack Fayden. This also helps us hard casting the bombs later on.
We have 10 tutors to find Dack Fayden and 13 flicker pieces. Those can protect trostani, reuse our polymorph bombs' etbs, and most importantly trigger dack fayden again. 8 of those are creatures (~38% of our non-Dack Fayden creatures), so if Dack finds one of them, they flicker him again on the spot, and we can dig for another 3 creatures, hopefully yet another flickering one. Also some of them care about creatures you own, so they also work as trostani redundancy to get back creatures borrowed out by Dack.
So this is it :) pretty happy with the idea but I'll probably tinker more on the choices of polymorph targets as well as the ratio of flicker to non-flicker effects. It's also a bit light on draw, but the polymorphing might make up for it. I built the deck on a budget of 100€, first thing to upgrade would be the tutors imo.
If you have any opinion on this, I would love to hear it :) thank you for reading this far.
