Top Ten Selling in May

Just grabbed the data for the top selling cards in May. The ROE is still the main best sellers this month.
Consuming Vapors is a very good rare card, 4 mana cost killing twice.
Ulamog, the Infinite Gyre, probably those blue control decks have been changing to this card.
All is Dust, suits for most of the deck, it has been very demanding since last month.
Tezzeret the Seeker....I am not sure why it is here, but probably there is a new deck from Japanese players around this card.
What do you think?

1. Consuming Vapors
2. Ulamog, the Infinite Gyre
