The whole point of Infect is to be stupidly, ridiculously fast. This deck is an attempt to lean hard into that fact.
The first step is creating a legitimate Turn 2 win opportunity, specifically the one created by Scale Up.
Turn 1: Forest + Glistener Elf
Turn 2: Scale Up + any combination of buffs equal to +4 Power.
I'm currently trying to decide on the right mix of Rancor and Scale Up - Rancor helps get that damage past early chump blockers, but Scale Up is key to the turn 2 win. Removing Canopy Cover (see below) puts more pressure on the Rancors to help me with evasion.
Exalted triggers continue to add value even in a mono-colored deck (especially with the introduction of Ignoble Hierarch). Including so many mana dorks and going with a mono-colored deck allows me the luxury of going lighter on colored mana-producing lands and I tuck in a Karn's Bastion to help get the occasional stall over the hump.
(EDIT: I've taken Canopy Cover - discussed below - out for the moment, experimenting with the quicker strike of more instants-speed buffs, but I still maintain that its a very effective and under-utilized option)
Naturally, mono-green lacks unblockable creatures like Blighted Agent, but it does offer the rarely seen Canopy Cover which can be even better. It's always a pleasure to lay it on a Glistener Elf turn two, have my opponent say 'what is that', read it, look at his hand, frown and think about his deck and then scoop. It happens more often than you would suspect. Having said that, I find Canopy Cover to be its most useful when you have to go into the mid-game; waiting until your opponent is tapped out and then casting an infect creature before immediately dropping Canopy Cover on it gives you a serious threat they might not be able to respond to.
