MTGO has a key you can hold down for "Tap a dual land for whatever the first mana is, probably because you just need to spend it for a generic cost." When I do need to tap my lands individually, because I want to keep specific colors up, it takes a lot of time to fiddle with selecting colors when it usually doesn't matter at all after the first color

Its the kind of card that turns one turn into the last turnyou cast it, then start chaining cheap creatures one after another, drawing cards the whole time
(Note that a devoid card like Eldrazi Displacer counts as both colorless for those cards as well as for Iroass devotion devotion only cares about mana costs, not color)
Even the original Pokmon TCG game from 1999 did quite well, exceeding 600,000 sold in Japan alone, and another million-plus worldwide
