Yog-Sothoth, Key and Gate

When Yog-Sothoth, Key and Gate enters, draw a card.
Landfall — Whenever a land you control enters,
you gain 4 life if this is the first time this ability has resolved this turn. If it's the second time, add
{r}{g}{w}{u}. If it's the third time, Yog-Sothoth deals
4 damage to each opponent and each planeswalker you don't control.
