This format is a blast (as evidenced by the massive turnout it generates).
You don't have to worry about being fast, as Razvan noted the way the time constraints break down you actually have MORE time per game than in sanctioned play. Only the slowest of decks have trouble getting 10 games in. If my record is 8-2 or better after 10 games I keep playing until I get my third loss since X-3 will always make the cut as long as X is greater than 8. I usually get about 15 games in (with mono black Void) and a pure aggro deck like gobbos or sligh can easily play 20-25 games if they desire.
Anyway...Raz's deck.
Utility 'Tog. I think the concept is fine, lets just concentrate on cutting some cards.
-3 Misdirection
Yes it is a powered environment but power is still relatively rare (a third of the field at most) so MisD'ing Ancestral, while wonderful in theory, is virtually never going to happen. Also consider that the best aggro deck, by far, is goblins. They will have few, often ZERO, Misdirectable spells.
+1 Intuition
Too good not too with 'Tog and the Squee/Bazaar engine. Tutors are that much better in 100 card. I want to add Vampiric but you are already pressed for space.
-1 Beserk
Great card but you can't intuition for it with one copy and that leaves only a Mystical and Demonic to find it with. Are you really going to have it when you need it? I think it is situational enough to safely drop.
-3 land
43 mana sources is a little heavy, I think you can get by with 40 considering how your curve looks and your card drawing. Which land...I dunno, you can decide that better than me I'm sure.
That would get you down to 100. Heck, you could probably go down to 35 mana sources, it isn't like anyone plays Void there.
