Staff of the X Magus vs multicolored lands
I thought I'd find an answer on this easily, but somehow it's more troublesome than I'd imagined. That, or it's a dumber question than I think it is, haha.
My question is, do the Staff of the X Magus (like my Staff of the Sun Magus or Staff of the Flame Magus ) abilities work on multicolored lands, or is literally just cards named Plains or mountains in addition to white/red spells?
It doesn't trigger for cards like Temple of Malice because those lands don't have the BLT Mountain.
