For reference here's my current list:

23 Land
4 Horizon Canopy
4 Arid Mesa
3 Wooded Foothills
3 Windswept Heath
3 Plateau
2 Taiga
1 Savannah
1 Mountain
1 Forest
1 Plains

20 Creatures
4 Wild Nacatl
4 Steppe Lynx
4 Qasali Pridemage
4 Tarmogoyf
3 Grim Lavamancer
1 Kird Ape

17 Spells
4 Path to Exile
4 Lightning Bolt
3 Chain Lightning
2 Sylvan Library
2 Fireblast
2 Umezawa's Jitte

15 Sideboard
3 Tormod's Crypt
3 Orim's Chant
2 Ethersworn Canonist
2 Pyroclasm
2 Krosan Grip
1 Kataki, War's Mage
1 Pyroblast
1 Red Elemental Blast

The only suspect cards are the number of Sylvan Libraries and the Umezawa's Jitte main deck. I'm not sure whether to run the 4th Grim Lavamancer or not. I hate drawing that card in multiples. Any ideas?
