With respect to the list below I added a forest in place of the lifegain land enchantment, since I was mulling way too much... you will see the results in this match. Game 1 is the stereotype of the match-up: we need to have that one turn to combo them and they have to have multiple snaps/familiars to stop us. Game 2 and 3 the sideboards enter play and the games can be tricky and played on edges. Game 2 was nice, while Game 3 I kept on the draw a very good mana hand but basically empty unless I topdecked something soon... I did and went all-in comboing T3 with little probability of success... then kept being insanely lucky :) After the match Parallax confirmed he had ephem and flicker in hand, but was mana-short not having drawn lands for 4 turns.

Micro-primer: 3 target creatures for freed (arbor elf, overgrown battlement, axebane guardian), 3 kill cards (Secret Door, Capsize, Valakut Invoker), tool box of 3-casting-cost cards, general drawing suite since Lead the Stampede is not very good with so few creatures
