I really want to do this myself: https://clips.twitch.tv/OptimisticMisty ... gBCWarrior
Polyraptor is so amazing!

Some dude did this against me on Arena. There is a lot of roaring and shooting and other special effects; when the dust settles, all your creatures are dead and the opponent has over 9000 polyraptors. It's pretty cool.

Wish I could figure out what was done. Way too quick for me this morning.

I don't know the maths exactly but OG Poly comes into play and triggers Forerunner which creates a copy which triggers forerunner and creates 2 copies, which I believe you then deny the first trigger of forerunner but accept the 2nd trigger so that all 4 Poly's get hit and make 4 more copies for 8 total copies and the OG Polyraptor with the Forerunner dying in the middle of the process.

In the vid the players do miscount a bit and the opponent kills his memes when he shouldn't have but it doesn't really matter because he is dead to a bunch of hasty dinos anyway.

There's a bunch of maths and explanation in here: https://www.reddit.com/r/magicTCG/comme ... ombo_live/

Now if only I had 4 Forerunners.

Nice. Need to see if I have any of the makings in my collection.
Thanks for the explanation guys.
Edit: Nope... nothing except one Regisaur Alpha

I finally pulled it off and opponent quit and then I did it again and was at 1 life, wish I could see the salt.
Also the end result is indeed 7 copies and the original.
If you can give the forerunner indestructible it can become an infinite combo even with Polyrators dying off you create more than what die and the Forerunne ris a may so it is fine.
