So is there any reason to do this over the pure blue/green version with easier mana, llanowar elves, more counterspells?
The Seriema feels nice but holy shit do you need something convoluted to actually win the game with it.

I haven't seen anyone come up with an easier combo, and if you play and lose any pieces of this you can't go infinite, and its not that easy to protect so they'd have to be tapped out. It would go;
>The Seriema/Jill in either order, if you already used it to start Kona you can recur it with Jill
>Seriema gets Ambrosia, who returns Seriema
>Seriema gets Worrywort, who returns Ambrosia, who returns Seriema
>Seriema gets Roxanne, who deals 2 damage and returns Ambrosia thanks to Worrywart
>Ambrosia returns Roxanne
>Roxanne deals 2 and returns Ambrosia
>loop two steps above 9 more times, for ~30 casts before lethal and another ~30 triggers with targets

Looks awful to play through
