Islandwalk (This creature can't be blocked as long as defending player controls an Island.)

Companion — Your starting deck contains only cards with mana value 3 or greater and land cards. (If this card is your chosen companion, you may put it into your hand from outside the game for as a sorcery.)

When Keruga, the Macrosage enters the battlefield, draw a card for each other permanent you control with mana value 3 or greater.

Whenever Pygmy Hippo attacks and isn't blocked, you may have defending player activate a mana ability of each land they control and lose all unspent mana. If you do, Pygmy Hippo assigns no combat damage this turn and at the beginning of your next main phase this turn, you add an amount of equal to the amount of mana that player lost this way.
