Blistering Firecat I might be giving Blistering Firecat more credit than it deserves, but its hard for me to see 7 potential damage for 4 mana and not want to take the risk of including this red card in my deck
We're spoiled for choices these days for what seven mana can buy you, between The Endstone, Ugin, Eye of the Storm, and Sire of Seven Deaths, but turning landfall into card advantage with The Endstone gets a huge nod in a format with Icetill Explorer, which can power out The Endstone on turn five
What is a Leader Card
Still, as long as I had a bunch of them in my deck, the upside of a free spell is worth the inherent risk of putting a colorless land in my deck
I probably play more enters-the-battlefield tapped lands than most folks, since my local environment with the other RC members is pretty slow, so I see how Tiller Engine might be something that I get a little extra mileage from
