The first card type to fall!

Tribal

Perhaps inevitably with so few cards, the first card type to be knocked out of the running is Tribal. The last survivor was Bitterblossom, which outlasted any of the non-Tribal Faeries to be the last of its kind.

Morningtide

Bitterblossom was also the last remaining Morningtide card, which means that the set is extinct just before the Top 32.

Darksteel

A rough day for Darksteel, whose last two cards - Skullclamp and Sword of Fire and Ice - both fell today to leave the set extinct.

Auras and Equipment

By sheer poetic coincidence, those same two Equipment fell in the same batch as Rancor, the last remaining Aura.
