Post Patch Praxis: Sentinel Edition

I have a weird habit of resorting to Heart of the Vault decks when there are format shakeups. This my most recent build I've been playing around in top 300 masters with.
Against aggro: very straightforward. Play big sentinels till they concede. 4th purify is recommended (in market) if you're seeing lots of aggro. The matchup isn't an autowin, but it's definitely a favorable one.
Against most other matchups: Bonding a Novaquake Titan is the only way this deck is winning a game against much of the field right now. It's incredibly easy to pull off and wins the game on the spot. Extra style points for giving it charge with Arcanum.

Oh, and be aware of the fact that acolyte and trail maker are explorers for extra stirring sand triggers.

NEW PLAYERS: this deck is very expensive and is only good in certain meta-games so maybe look elsewhere if you're on a budget.
