Summary: I use Lizard deck. So do I like this card?
Comment: Flame Lizard Commander is definitely one of my favorite card as a Lizard deck user, but I can’t still decide about this card. Fire creatures generally have ability to combo and reduce summoning cost, so as the game goes, if everything goes well I start to accumulate some mana.
Mana cost of 6 with almost minimum of 6 damages (with proper use) to opponent seems great. But the Subtract summoning cost ability is limited to Fire fields. Given cost of 6 mana for this creature, by the time I get a chance to summon him, it is most likely that I have used up other fire fields with other allied creatures. Having said this, proper use of this card sort of gurantees destroying 2 enemies at once. So by this strong attack alone may suffice its use.
Hmmm.. Maybe one in a deck.
