14x Borderpost
Or more specifically:
1x Firewild Borderpost4x Fieldmist Borderpost1x Wildfield Borderpost4x Mistvein Borderpost4x Veinfire Borderpost
These cards are the major backbone of our mana, they allow us to have a single land in hand, and know we have all the mana we need. They are slow, sure, but the get us the win, and the combo is fast enough to compensate for them.
4x Mox Opal
This deck runs Mox Opal as it's fastest way of making mana. It does that job well, and can help combo out better than the borderposts can. Sadly, I can only run four, and they are legendary.
4x Mind Stone
Are you sick of mana rocks already, I am, but this is one of our few ways of drawing cards, so I guess it is pretty good. It also makes for some really fun plays, like tapping two lands for a Mind Stone, tapping it for a borderpost, and bouncing one of the lands, stuff like that.
4x Street Wraith
In the same way Mox Opal is free mana, this is free card draw, and sure, that isn't free, it costs two life, but a combo deck can pay two life if it means infinite mana and damage.
4x Dimir Infiltrator, 4x Muddle the Mixture, and 4x Shred Memory
These twelve are our tutors, they give this deck an edge over other combo decks of the similar kind. Without them, we'd never have our combo, and if we replaced them for Serum Visions, our deck would be the worse for it.
4x Isochron Scepter, 4x Dramatic Reversal, 2x Elaborate Firecannon
This is our combo, we need it to win, if you question why we only run two Elaborate Firecannons, it is because they do nothing without the rest of the combo, whereas the rest of it makes infinite mana, and at least Dramatic Reversal can make mana by itself.
