Let's build a $50 Duke Ulder Ravengard EDH Deck 

Glad I found someone else confirming the "No death triggers" thought I had. Was browsing EDHrec and saw that one of the #1 rec'd cards was "Atsushi, the Blazing Sky". Glad to see that someone else caught that

Something everyone has missed when building duke ulder is that you can play things like Ganax, Archon of Redemption, Forgeborn Oreads, Coercive Recruiter, and Scourge of Valkas. These guys notice eachother, and themselves, and thus the more players the more they do. It's exponential. With 3 opponents you get 6 triggers. With 4 opponents you get 12 triggers. With 5, you get ...20. Anything times 20 is insane, even if it's just 1 damage.

After building the deck and playing a budget deck. I found that the deck needs 20 ramp cards and ways to filter until you find your strong etb effects. You really only need one good creature to give myriad. There is a bunch of ramp because your commander will die. At least 1 or 2 times. By then it'll cost 8 or 10 mana. So running a bunch of 1 or 2 mana spells that can give your creatures protection is the best thing you can do. I found that the white ramp catch up cards are amazing in this deck. Imagine this start, 4 lands a 2 mana rock, and a creature that searches your library for a land if one of your opponents has more lands than you. You can get your commander out turn 4 and then you swing with the creature that catches you up to the other players and by turn 5, you are sitting on either 8 or 9 mana. Just enough to cast your commander again or some other bomb as well. Kor cartographer and solemn simulacrum are amazing in this set up, and white has a bunch of catch up cards. Play the 2 bounce lands you can play and lotus field. Make it so you always have less lands than your opponents. The deck is gross if left unchecked.

This is another deck I want to build because it looks fun

I do like this commander but I play one in Commander Portyr, giving something myriad works well with her ability. Portyr doesn't just discount cards exiled with her ability but cards from exile and its great with adventure and giving a creature myriad means that you can realisably get the maximum reduced cost

I am wondering if mirror box will be good giving up to +3/+3 to the non token creature

Do you get death triggers if the myriad tokens get killed via blockers/sac?

can you do wilson the bear?

does myriad stack?
