PPTQ Top 8: Not Red Midrange, Masters 25 Draft, 4th Place (Limited)

Main Deck: Not Red Midrange (3-3)

Highlights:
Multiple games with triple Cloudblazer.
Beating Armageddon thanks to a sideboarded Primal Clay.
Getting multiple Cultivates after switching from Blue to Green in Pack 2.

Lowlights:
Having to switch Blue for Green halfway through Pack 2.
Quarterfinals, Game 3: I kept playing lands because I wanted to double spell with Vessel of Nascency, Fierce Empath, Cloudblazer, or Baloth Null (and I wasn't thinking about Armageddon, which did not appear in the first two games). My opponent got up to 5 cards in hand with Boros Aggro, which was perplexing, then cast Armageddon. I only won by Morphing Vesuvian Shapeshifter in response and having it copy my 2/2 Flying Primal Clay, then attacking with both for 4 turns.
Semifinals, Round 3: I'm at 15. My opponent attacks with Bloodhunter Bat and Ghost Ship. I block the former with Cloudblazer so I can bring it back with Baloth Null since I have Fierce Empath in hand and leave the Ghost Ship unblocked, going to 13. My opponent's second main phase play is a previously unseen Triskaidekaphobia. I draw Vesuvian Shapeshifter with my 1 Island and a Prophetic Prism, so I am able to clone Cloudblazer . . . except it's dead, and therefore, so was I.

Additional Comments:
It took a judge call to determine if Vesuvian Shapeshifter becomes a 2/2 with Flying when copying Primal Clay or just a 0/0. I should have at least considered this.
