But X's first ability says you can, so you can
Even if you feel like the precon may be a bit lacking or you want to play it differently, its easy and straightforward to upgrade
As the other 2 players had no board they scooped to end the game so we could start the next, giving me the win
Let's check them out: Lands, Mana, Ramp, Rocks Let's start with mana rocks
IMO this set is kind of underwhelming and only worth it for Mantyke, but of course we have not seen all the cards in the set so there could be more of course
However...this is only three times as much mana as we could have gotten by using any other animated artifact or enchantment with Hanna, Ship's Navigator (since any of them can be sacced to Phyrexian Altar)...and probably less mana than we would get out of bouncing and recasting Doubling Season (assuming there are multiple Minion Reflectors in play, once we get to the second trigger we will most likely be putting much, much more than triple the permanents into the battlefield)
