Dies to Removal

Don't get me wrong, Hero and Scarhide are good cards, but if I'm already diluting my manabase to use Butcher and Mardu Ascendancy, I think Swiftspear and Soldier would serve me better. I think Soldier is especially good with so many multicolor decks in the format.

Of course, only testing will determine if it works. Who knows, I might be deluding myself.

Looking for opinions on this list:

[DECK]
Lands (23)
4x Battlefield Forge
4x Bloodstained Mire
4x Caves of Koilos
4x Mana Confluence
2x Mountain
2x Plains
2x Swamp

Creatures (24)
4x Bloodsoaked Champion
4x Butcher of the Horde
4x Goblin Rabblemaster
4x Monastery Swiftspear
4x Soldier of the Pantheon
4x War-Name Aspirant

Spells (14)
3x Mardu Ascendancy
3x Ride Down
4x Stoke the Flames
4x Titan’s Strength

Sideboard (15)
3x Chained to the Rocks
2x Despise
2x Harness by Force
3x Magma Spray
1x Purphoros, God o the Forge
1x Ride Down
3x Sorin, Solemn Visitor
[/DECK]

Haven't even tested yet. I know the mana is a little greedy at only 22 lands, but seeing as I have 14 untapped sources of R, W, and B, I should be able to cast any of the one-drops 90% of the time. It's kinda similar to Saito's list, but I think his list didn't have the mana to support the white one drop.
