In aiming for 60 cards, head closer to 22 lands, 20 creatures, and 18 spells. Weight your spells by what they do: damage, life loss, combat tricks, enchantments, etc.
Start by taking out everything with a Converted Mana cost greater than 4.
From there, prioritize you're cards with converted mana cost 2 down to twelve cards.
Fill back in with prioritized options for those greater than 4. It is around turn 6 the match should be near to decided.
Consider heading towards a deck full of cheap creatures and life loss/gain effects that feed into the interaction of Sanguine Bond and
Exquisite Blood.
