This is not far off from any grixis delver or grixis control list so Ill just explain why I did things that I see different from others of the like.
First I HATE Gurmag Angler! Lol! Seriously, there is no time ive ever drawn it that I wanted to have it. So I put in Tombstalker. One more black mana is no problem and a great tradeoff for the flying aspect.
Tasigur, the Golden Fang is now only a 1 of and will probably stay at that. Need the graveyard control that 2 delve cards can give me MB and then 2 additional instant speed delve tools in the SB.
There are no Young Pyromancer's as they are amazing they are just not effective enough agianst enough. Some may appear in the SB though.
4
Burst Lightning
. It was 2 but I have justified the maintenance of 4 through my bad matchups and that I need burn. Also benefit from more in the way of less regret using one for 2 damage.
Vendilion Clique Devastating at the right moments, Game changing in others. The 3/1 flyer on the flash alone is back breaking. Keep trying to justify more but can't.
Now my favorite MB change is a single
Rakdos Charm
. This card is money! People who think Spellskite is splinter twins bane hasnt seen the versatility of
Rakdos Charm
spellskite doesnt win it for you! First to talk about splinter twin, the all creatures option if you are on top of the damage being dealt and keeping the amount of potential creatures he has to make on his assumed winning turn you can win. Basically splinter twin generally runs 4
Deciever Exarch
and 2 Pestermite. Assuming for description only that you are both at 20 life, they play deciever (which is more likely) they have to make 20 to win so rakdos charm wins for you, pestermite however only needs 10. So be sure to deal some dmg to the face so they have to make as many creatures as they have life. Now mode to destroy target artifact.....yeah, and then exile all cards from target players graveyard..... Ok besides the obvious implications get this, Pyromancer Ascension ability triggered for second counter on the stack.
Rakdos Charm
exile graveyard in resp... no second counter. This card has so many implications and has 3 in the SB.
There are a couple different SB things that at first glance might be bad but ill explain.
Magus of the Moon I want a blood moon I can swing with agianst every single one of my bad matchups especially tron.
Logic Knot 2 mana counterspell with delve..... love graveyard control especially with a Tasigur, the Golden Fang.
Murderous Cut Is SB because of the delve mainly, but kill for B is great.
And 2 more Terminate Cant have enough cant be regen kill on instant speed. Especially in this format!
Ok thanks for reading yall! Hope you have a great day
