Planeshift, Uncommon. A 4/2 for 3R would have been a fair creature for a limited environment. Taking a Bathe in Dragonfire onto it made this card ridiculous when it was in standard. So you play it, probably kill something, and then swing for 4 damage on your next turn. That sounds like a pretty good deal to me. If you play this in a Flicker deck or any other type of deck which abuses enters into the battlefield triggers, you can get a lot of mileage out of this flame-spitting lizard-dog-thing. BEHOLD!
On a personal note: if I could ask for any one card to be reprinted, as either a full reprint, or merely a functional one, it would be this one. If they wanted to do something special for me since I’ve been a fanboy since 2001 (yeah, I totally just said how long I’ve been playing), they’d give it flash! But in all seriousness, aside from the fact that I feel like the game has reached a level of average power to where this card would be good, and yet nowhere near the monster it was in the past, Flametongue Kavu is one of the first cards I remember playing when I first learned the game and it has sentimental value of sorts for me.
