Blue-Red Delver isnt a bad matchup per se, but it has definitely gotten worse now that Delvers creatures all have flying, and Murktide Regent in particular is an issue due to how quickly it can close out a game
Though other cards that have been revealed so far are also pretty exciting, Tritons Trident, Rapunzel, Mickey Mouse and Mulan, for example, the Ursula, Sea Witch Queen card is one we cant wait to get our hands on
In English, one such card is the 3rd Edition Serendib Efreet, which has the picture of Ifh-Biff Efreet from Arabian Nights instead
Barrin, Master Wizard (Saga/Legacy/Destiny) Barrin, Master Wizard, though a very fragile 1/1, basically turned every card on your side of the board into an Unsummon
Mulldrifter is rather like Think Twice in that it is not wonderfully efficient card draw but offers enough flexibility to offset this
