The end result is that rather than having 37 lands in my Commander decks, in a post-MDFC world, I generally have 3132 "real" (non-MDFC) lands, but thanks to the eight or nine MDFCs, the total number of lands in my decks actually increases to 40 or 41
Each Demo Game Pack contained 24 Shadowless Base Set cards (a fixed selection, not random) plus a "Demo guide" rules booklet
Obviously, you need to have 4-5 cards with Proliferate to really unlock this, but that doesnt seem like a big ask, and the floor of the card is so good that it is hard to look at this as anything less than amazing
In fact, the sets were widely considered failures by the game's players and designers, which is weird, because for me they were, at the time and even today, the best sets available
Both characters then deal damage to each other equal to their Strength (the attack power stat on the card)
