Legendary Planeswalker - Nissa 

Landfall - Whenever a land enters the battlefield under your control, put a loyalty counter on Nissa of Shadowed Boughs.
+1: Untap target land you control. You may have it become a 3/3 Elemental creature with haste and menace until end of turn. It's still a land.
-5: You may put a creature card with converted mana cost less than or equal to the number of lands you control onto the battlefield from your hand or graveyard with two +1/+1 counters on it.

Nissa’s middle ability overwrites any previous effects that set the land creature’s power and/or toughness to specific values. Other effects that set these characteristics to specific values that start to apply after the ability resolves will overwrite that part of the effect.

Effects that modify the power or toughness of the land creature without setting it will apply to its new base power and toughness no matter when they started to take effect. The same is true for counters that change its power and toughness.

If a card in a player’s hand or graveyard has X in its mana cost, X is considered to be 0.

The creature card’s converted mana cost is checked only in your hand or graveyard. You may put a creature card onto the battlefield whose converted mana cost becomes greater than the number of lands you control once it’s on the battlefield, most likely because it enters as a copy of another permanent.
