Beat of the Thorn

This deck uses creatures that can deal direct combat damage to a player, in combination with Biorhythm. The Biorhythm lowers their life, and then you deal combat damage directly. If the opponent uses beatdown, white or otherwise, use the counterspell with an Isochron Scepter, or with big creatures, use fog or tangle. The Slagwurm is for use against control decks, and familiar ground prevents losing too many creatures, as with Verdant Succession. Use Planar Portal to search for combo cards, and use lens, bloom, burgeoning, growth, and temple to generate enough mana to play your cards quickly. What do you think?
