a must have for GR decks, got four of them in my MTGO G/R deck.. and they are awesome.. Say u have a mountain, forest and a flamelit thicket.. and u need to play one of your flame javelins.. U tap the fire-lit thicket and forest to create two mountains.. then tap the mountain u already have and bam, 4 damage to target creature of player. Fire-lit thickets are awesome and they dont come into play tapped.
