There's no official deck-building challenge for this week, but that doesn't mean you shouldn't go out and build decks anyway
Alternatively, you can make each cell an exact size by right clicking the top of the column (where the letter is) and selecting resize column
Of course, Dryad of the Ilysian Grove helps with this, but it doesnt hurt to run them nonetheless
Picking just one Magali art is extremely difficult, but the Chandra Planeswalker from the Signature Spellbook: Chandra is what happens when all aspects of card design converge to create greatness
Some of my favorite cards include priming your creatures (Berserkers' Onslaught, Glorious Anthem, Mass Hysteria, True Conviction, Collective Blessing), giving everybody something fun (Kami of the Crescent Moon, Eladamri's Vineyard, Well of Knowledge) or something that can help folks make the most of a problematic situation (Fecundity, Silent Arbiter, Oath of Lieges) or cards like Revelation or Field of Dreams
This means you can play your Fairy deck in GLC but will never be able to add more Pokmon unless The International Pokmon Company surprises us and starts printing them again
