Another one of those letter-matter cards that isn't acorn. Huh. We'll have to wait to see how easy an alliteration is across these stickers, otherwise those names are just a +1/+1 counter that hates on Pithing needle. For example, this sticker sheet alone is just +1/+1.
Here we have possibly the greatest sticker sheet in Unfinity. Good pumping ability, Hexproof, Colossal Dreadmaw stats, an acorn, a hat and, most important of all, that absolutely adorable Liliana doll. A mint version of this sticker sheet will be worth big bucks methinks.
The Vehicle is fine, 4/5 flier for 4 if you get the alliteration bonus, but only when attacking. Can be further augmented, sure, but getting 3 or 4 sheets with a matching alliteration will be pretty difficult and I dunno if the payoff is worth it since as with every Vehicle it's pretty dead without any creatures.
Can somebody explain to me why Goblin Cruciverbalist is an acorn card, while this vehicle, that also get pumped based on letters appearing in a word, it's eternal legal?
Well, for starters, memory issues, language barriers and the ever-growing pains of defining what constitutes a "word". This one is far easier to track, has only a limited dictionary of stickers and while it doesn't translates perfectly for other languages, I'm pretty sure the headache of a Japanese player trying to make up alliteration out of English words will be far less excruciating than trying to spell something on their native language using an English alphabet and then trying to figure out how to calculate a word's length out of it.
