This is my main tournament deck, i find mono coloured deck are very consistent which you need in tournament when it comes to the knockout stage, nothing is worse than finally getting to the knockout and being knocked out due to bad draws. I choose white since i find it as a very balanced with it being able to boast a good offence while have a strong defences.
It seems to work really well as Ive been winning or placing in every big tournament Ive been entering with this deck.
In early game its uses Champion of the Parish to have an edge in power while having Gideon's Lawkeeper to control a turn two delver flip and signal pest battle cries.
Having Grand Abolisher to put a stop to spells like counters, fog, snag, burns and not to forget the player who tries to miracle in your turn.
I found Elite Inquisitor to be a strong early game presences as well as late game with power ups with it being able to put a stop to common deck such as Blue/Black zombie and Blue/Green grave power.
Using Fiend Hunter and Oblivion Ring to remove any permanent that make life difficult for you, having Cloudshift to help with a Fiend Hunter combo and a bit of flicker protection.
Once Fiend Hunter and Oblivion Ring remove any obstacle Angelic Overseer, Hero of Bladehold, Mirran Crusader and any powered creature move in to deal good damage.
While having Ratchet Bomb as a tailored board wipe or a anti token card with Norn's Annex to make life difficult for any attack based deck, even if they are white it slows them down a lot if you can get it out on turn 3.
Side boarding in Grafdigger's Cage to stop grave based decks like flashback and having Divine Reckoning to help with the board control always choosing ether a Fiend Hunter or Mirran Crusader while having Angelic Overseer being able to survive.
Silver-Inlaid Dagger and Elite Inquisitor just help with add more aggro speed in early game.
