While MTG Arena doesn't allow players to trade cards between one another, like paper MTG or MTG Online, players can use the Wildcard system in MTG Arena to craft exactly the cards they need
Its primary card is The Black Cauldron, a three-Ink item that lets you move a character from your discard pile under the cauldron
Gandalf the Grey Gandalf the Grey has several good modes, but its best is easily its ability to copy spells for free
Hakbal of the Surging Soul is my personal choice for Merfolk Tribal because he is more consistent, he is alone a great ramp/draw engine and scales greatly with going wide
Eh, you only really need his tokens, anyway
Couple that with the fact that some ridiculously strong items are being released in Into the Inklands and undoubtedly we are going to see the rise of a new archetype and best Lorcana deck: Sapphire/Amethyst Items
