Well I played my first ever draft (4/3 ACR), It was pretty terrible since I really didn't have too much of a clue. Unfortunately I didn't know about the draft recorder (which would obviously help me improve - lots of room there)
I did manage to win my 1st round on the 'strength' of necrogenesis and vithian stinger. I think my opponent misplayed a fair amount, and I made 2 glaring mistakes that gave him an extra turn or two - Knight of the New Alara can make things big. Second game I found all my removal and won easily as he didn't make a play till turn 5.
Duotianshi203 crushed me Round 2. I think he's one of the better players from what I've briefly researched.
What I recall -
1st pick Tidehollow Strix (don't ask)
2nd pick Magma Spray
3rd pick Vithian Stinger (might not be exactly right).
Passed on a Thornling that I probably should have just taken because I don't think I took anything great in that spot (pick 3 I think) Didn't realize it was a 4 tix card
Based on the pool, anything glaring terribly bad in the build, probably should have ran etherium main (maybe brainbite). I never got to play defiler, though he's not amazing in my deck, but I still liked the potential.
Draft cost 11-12 for the packs than 2 tix for most drafts. There are also no tix/pax drafts that cost (3 packs or 12 tix).
