Alania does cost quite a bit at five mana, but the ability to copy your first instant, sorcery or crucially Otter spell each turn can snowball quickly
Lets take a look at some other top players that compliment Prosper, Tome-Bound
And now we end the artifacts with the last 'expansion-hoser' card, Apocalypse Chime , which destroys all Homelands cards for the total cost of four mana
First, it gives them pseudo-vigilance, meaning theyre around as blockers (assuming they survive combat)
Surely having to pay three mana to do nothing but bring this creature to your hand is bad enough to neuter the poor creatures, right
In three colors, I think a deck using artifact creatures to sacrifice for value and Reyhan, Last of the Abzan to make Silas huge would be fun
