This is probably one of my favourite decks to play. When I play I like huge stacks and multiple triggers.
With this aura/hexproof deck, dominate the opponent with a hexproof, unblockable pimped up badass.
When you're rocking an Invisible Stalker with ciphered Hidden Strings, Curiosity, Invocation of Saint Traft, Spectral Flight and Battle Mastery you'll have no end to card draw, mana ramp and damage output.
The main problem with the deck thus far is that you must have an Invisible Stalker or Geist of Saint Traft to actually do anything. I don't enchant the Judge's Familiar as it doesn't have hexproof and dies too easily. That's where I had considered adding in Swiftfoot Boots that way even if I didn't get the stalker or Geist I'd have another option, and then later if i do draw one I can switch the boots over to give haste. The other option would be switching the judge for Slippery Bogle.
Combos:
Battle Mastery + Hidden Strings + Invisible Stalker
= tap or untap up to 4 permanents (can be land to play more things in second main-phase)
Battle Mastery + Curiosity + Invisible Stalker
= draw an extra two cards every turn
Invisible Stalker + Invocation of Saint Traft
= 4/4 flying angel every turn.
Geist of Saint Traft + Spirit Mantle
= 3/3 hexproof, protection from creatures (unblockable) and 4/4 flying angel every turn.
I'm still trying to work out a sideboard. I think it'll be a total switch up to throw off opponents. Maybe 4x Mana Leak, 4x Detention Sphere and some more control.
If the opponent is playing a lot of board wipes bring in your counter spells and make sure you keep the mana available.
Let me know what you think, any suggestions and support would be great!
