Geez I must be getting forgetful, playing catchup for 2 days now >.>
Anyways, Magmortar MT...well, no one used it, because Magmortar SW was released next set and completely outclassed it lol. Statwise, 100 HP is nice for a Stage 1, +30 Weakness to :water: is bad, no Resistance is common, and :colorless::colorless::colorless: to Retreat is expensive. Smoke Bomb is a bit pricey at :fire::colorless: for 30, but the 50/50 chance of not receiving damage next turn is nice. Flame Drum is meh; now, 80 for :fire::fire::colorless: normally isn't bad, but the need to have a dumb Magby under Magmortar to avoid discarding 2 Energy from your hand is eww (unless your goal of course is to discard Energy...but it shouldn't be usually).
Modified - 2/10 (Once the SW one came out, I think everyone forgot this thing existed)
Limited - 6/10 (Not too bad in ways...Smoke Bomb can frustrate your opponent, and you should have enough excess Energy cards in hand to use Flame Drum occasionally)
Unlimited - 1/10 (Bad bad bad)
