I've had pretty good success against Ichorid. I just side in 3 or 4 Crypts and play carefully. Get 1 or 2 threats on the board, then always keep some mana open for Path or burn. You have to be prepared to burn your own dudes during your opponent's draw step to get rid of Bridges, if need be.

EDIT: ninja'd

EDIT 2: Forgot to mention, 'clasms are good to SB in against Ichorid, too.
