A few thoughts:
1) Why are you sitting on Verdicts without some
Unsummon effects? It strikes me as though wiping the board is the last thing you'd want to do, given that your guys are hexproof and potentially unblockable (i.e.
Invisible Stalker). Sure, it could help if they're getting enough creatures to overwhelm you, but you could easily handle that with
Sphere of Safety considering how many enchantments you're already sitting on. That or just toss in
Pacifism/
Arrest/
Oblivion Ring as those serve as removal while also giving you more
Ethereal Armor pumps.
2) On
Madcap Skills I agree with what you've been saying across several postings that it has potential, but the largest potential is when it's paired with
Alpha Authority or even something like
Armored Transport. Otherwise, I can see where it still gets hit by the 2-for-1 trade everyone is saying.
3) It might seem silly, but I'd actually think about adding
Divine Favor in here as these sorts of hexproof decks are likely to run into
Rolling Temblor. I can honestly say I've started mainboarding it in any deck I play that has red for the expressed purpose of dealing with Geists and Stalkers. The added toughness could easily take things out of range.
4) Perhaps some
Negates could prove useful (likely SB). One
Paraselene and you're back to relatively small scale stuff.
5) You'll definitely want artifact hate in the SB otherwise
Glaring Spotlight will totally ruin your afternoon. Given the sudden rise of these decks and the existing popularity of GoST, I can see this card in EVERYONE's SB in about 2 weeks.
