1mana monsters

Well, if you can get control (not hard if you play early soldiers en masse, I'd think), then you simply attack every turn where sensible. You bouncesnipe on your own turn in response to the opponent playing a new monster, thus maintaining a very cheap control.

And while you will hit the 5 monster maximum, you'll probably hit it on turn 3 or 4, enabling you to take control before the opponent can really do much.

So yeah, I'd say go with x2.
