Magic the Gathering XXII: Where Puns Go to Die

[Klorox]

Hey guys. I'm just getting into M:tG for the first time in many years. I used to play in local tournaments but quit during Ice Age.

Anyway, I did some searching and thought this blue and red deck built around a card called Kiln Fiend was really cool. Then I found that card was no longer legal in Standard play.

Here's the deck I came up with based off the idea I liked. It's based around quick creatures and pumping them up with instants and sorceries. Most of the creatures inherently get bonuses when an instant or sorcery is cast, making these swarms of attacks even more powerful. I also have a lot of cheap cards to help me draw more cards.

Land (21)
4x Highland Lake
4x Wandering Fumarole
4x Shivan Reef
2x Island
7x Mountain

Creature (19)
4x Abbot of Keral Keep
4x Elusive Spellfist
4x Insolent Neonate
4x Stormchaser Mage
3x Zada, Hedron Grinder

Instant (16)
4x Expedite
4x Titan's Strength
4x Rush of Adrenaline
4x Sure Strike

Sorcery (4)
4x Slip Through Space

Please let me know what you think, and what I can do to improve the deck.

I'm already wondering if I have enough land. I'm also wondering if I should add some minor burn spells, a counter spell, a couple of Jori-En, Ruin Divers.

TIA
