Not sure how I was liking mono-red goblins so I decided to give Mardu a try since Mardu Ascendancy seems really good and who doesn't love Ankle Shanker. Need suggestions on landbase and sideboard. Other suggestions also welcome.

Edit: Fixed up the sideboard a bit from feedback I got. Maybeboard is now a list of cards that could go in the main/side.

Not sure if I need some burn/removal main or maybe more frenzied goblins? Any help welcome.

Edit 2:

Out: Main

4 Sub Scout 4 Glory Chaser 1 Frenzied Goblin 1 Obelisk of Urd

SB

2 Siege

In: Main:

2 Siege 4 Stoke 4 Searing Blood

SB:

1 Crackling Doom 1 Obelisk of Urd

Edit 3: Trying 2 searing blood main/side and 2 crackling doom side/main. I kind of want 4 searing blood but its more likely to be a dead draw against some decks. Going to 4 of either of them depending on what I am up against.
