Vectis Unbound

So Elbrus was my very first mythic so naturally I'm kind of attached to him but he's a Tough card to effectively use. I'm also a huge fan of artifacts so I thought I could try to put together an artifact deck based around getting him on the field and transformed.

I'm a casual player so I don't bother keeping this tournament legal in any way. I would love for this to become a competitive deck (in casual against my friends) though so any comments or help with this would be greatly appreciated!

I'm not an amazing deck builder, but here's how it's supposed to work:
Start off with etherium sculptors to speed up getting out vectis agents and dimir keyrune. The keyrune is probably the key (haha) to this deck because it produces mana to help ramp to Elbrus, can be an unblockable creature to transform Elbrus, and is blue as a creature so it will get the grand architect boost. If all else fails you can swing every turn with the boosted rune to end the game. Vectis is bigger and unblockable when you need it to be. Grand architect boosts runes and puts the sculptors to work producing mana for elbrus. The strix can be both offensive or defensive keeping your opponent from attacking out of fear or if need be serving as a method to transform Elbrus due to it being flying and a deathtoucher. And most importantly it's cheap. Phyrexian colossus is a secondary win condition or you could go overkill and equip Elbrus since the colossus can only be blocked by 3 or more creatures. Hidden strings for untapping colossus, tapping out opponents blockers, and creating blockers for you after the unblockable a swing through. It's be better as an instant but we can deal

• Unblockable
• Casual
