Then this drops on the second turn and then will last as long until killed by a foe, and if you went first, then Arcane Signets and Mind Stones are getting tapped or you get a free 1/1 and then on the third turn you get Manalith, and then don't forget this is dorks too, so everything from Reclamation Sage to Sakura-Tribe Elder to Mulldrifter will ETB tapped for blocking purposes unless you get a free Vampire
Higher quality than a real magic card
Alphinaud Leveilleur* 4 Mana for Alphinaud is a lot, given what else you can get in card draw there, and the fact its only on your second spell each turn combined with a poor size make this a creature you probably leave out of your party, unless you are wanting to make use of its partner
In addition to its rarity, Arthur is quite strong, with an ability that is likely to be leveraged by many serious Lorcana players
But timed right, this ability can end games
Having a way to handle big threats while also being able to board control against enchantments AND interact with the graveyard at instant speed for 1W is really great
