Twisted Grixis Dagger Burn [post Rivals eddition] (Standard)

It's basicly the "Dagger burn V2" deck from SaffronOlive (MTGGoldfish) with one mountain replaced by a scavenger grounds. It adds a bit of graveyard hate to the deck despite not having a single sideboard slot available. Cutting a mountain is harmless for he strategy because there is not that much red source needed compared to blue or black ones. And you never ever need 2 red sources on the board at the same time.

This is a post Rivals of Ixalan deck, so I cutted the ferocidontes and replaced it with Tetzimoc, Primal Death wich became an alternative win condition, it's a big creature that wipes our opponents board when it touches the ground (Nergigante style for MHWorld players around !) and a Deadeye Quartermaster to find our dagger when we need it. The Quatermaster synergises very well with the Panharmonicon strategy and help set up the kill. This card is basically a 5th dagger packet with a blocker.

As the mechanic of the deck, it's always the same, burning the opponent while playing dowsing dagger. We still got a lot of control and looting and scry, etc..
The sideboard is made to adapt to every matchup possible in the actual meta.
It has a pretty decent matchup against Approach and U/B control but may suffer a bit against red aggro, especially on the first round. This deck needs a bit further testing against dino strategies and simply destroys token decks (they suicide themselves, it's quite funny to watch). Merfolk is an average match as we have a lot of removals and some sideboards wraths but the hexproof part of the merfolk tribe may be annoying nonetheless.
