This creature has the effect of allowing you to play two additional lands each turn, which can be silly and sometimes even ridiculously strong if you include the right land cards and draw power
Deckbuilding around mythic rares means planning your entire strategy with those cards as the centerpiece
Then when your foes discard lands, you make free 1/1 Bats with flying and Black, so that's a win con Waste Not for any lands discarded like with cycling or channel as well as to this attack trigger
If youre not familiar with the Creature type, nearly every single Hydra comes in with a bunch of +1/+1 counters on it, so it sort of belongs here, though youre more likely building a tribal deck with them, we did feel they deserved a shout out
Copying a creature and giving it a combat research type effect is really nice
