The pair will join Gus Hansen, who was announced last week as the first member of the new Full Tilt team.
Dwan was previously a part of Team Full Tilt before Black Friday; in fact he was the last member to be signed to the team one step beyond simple 'Red Pro' status. He and Gus Hansen are, thus far, the only players from the old team to return.
Blom first burst onto the online poker scene at Full Tilt's cash game tables in 2009, taking on the likes of Dwan and his fellow Full Tilt teammates at dizzying stakes with relentless aggression.
He was signed and unmasked by PokerStars in 2011, before he mutually parted ways with the site - clearly, he is a better fit for the high-octane cash game action that Full Tilt Poker is famous for.
Full Tilt Poker will relaunch on November 6. For more information you can see our recent news:
