Infect deck capable of killing fast and making friends. Based on infect decks that have been performing well at sanctioned events.
Sideboard is still being worked on. But here are some basic sideboards using this current board vs common match-ups.
Basic mulligan rules:
If you don't have an infect creature in hand, toss it. Even if you have a Gitaxian Probe, it is too risky to waste an entire turn hoping to draw into your win condition creatures. Note: Inkmoth Nexus obviously counts as an infect creature.
This deck preforms well due to its speed, the longer the game goes, generally the worse infect does.
Tricks of the trade:
Example of a T2 kill hand barring no answers to the T1 Glistener Elf.
Wooded Foothills, Become Immense, Glistener Elf, Windswept Heath, Mutagenic Growth, Might of Old Krosa, Gitaxian Probe
Play Gitaxian Probe for 2 life to see what you're up against, then play Wooded Foothills or Windswept Heath on T1, fetch Breeding Pool and shock to play Glistener Elf. 2 cards in GY
Turn 2 play second fetchland and fetch a second Breeding Pool or Forest, then playMight of Old Krosa in Main phase, followed by Mutagenic Growth for 2 life which puts 5 cards in GY. Declare attackers, delve for 5, and pay one mana to swing with Become Immense for 13 on T2.
This may seem obvious to more experienced players, but some newer infect players do not immediately recognize the usefulness of the delve mechanic
