Furnace Punisher card seems to have several bugs
* I have seen it not trigger and not deal damage to myself or the other player, when it should punish both. As a triggered ability, it had not been countered by another permanent's rules text.
* I have seen it trigger and punish a player (my opponent) when they had one plains and one swamp, both basic lands. This should not have triggered and it should not have caused 2 damage.
* In the cases where it glitches it seems to glitch when you have non basic lands, AND basic lands.
* In the cases where it did not glitch it seemed to have ONLY non basic lands or ONLY basic lands.
