Belcher gets around a welder by Playing Severence first then Casting tinkering the belcher and activating it at the same time. Flame Vault is keep and allows you to just combo out. In all the games Ive played CS vs Gifts with Vault maybe 1 out of 100 games it lost cause of a welder but probably 20-30 were won because it had Flame/Vault. I think Flame.Vault is much better and it mostly comes down to play style since it shouldn't matter when your playing the deck right anyway since you can walk into more mana to activate the belcher and or take an extra turn for Vault/Flame. I would run Flame/Vault anyday over Belcher/Sev No questions.
here in the ne, i dont know why, but belcherlists seem to post higher results. at waterbury, day 2 there were 2 t8 belchergifts and 0 flame vault, along with misc. amounts of tourneys from gp philly vintage (1 belcher 1 flame 2 MD), where i took belcher to the finals and split with eli(for like the 3rd time)..he was Playing Md, and when i asked him why, he just kinda laughed. at myriad games, there were 0 t8 flamevaults where some kid t4ed with another belch/sev deck....At the last 2 beanie tourneys, belcher

won it against stax and t4ed the second day,while flamevaulte and andy sat to the side..(Although I did like the musical performance of brassman......GG's: they make up for all their 2nd place finishes with their musical talents!!!!)
i havent seen any other oppposing gift decks running flamevault in the t8 lately, and belcher has been plowing the way for me...it pulls out random hiccups for 24 and sev PWNS in the vast field of control that the ne is known for, but like i said, its just your own opinion.....
Stupid outlaw...that foil thirst was mine!!!
