A friend and I were trying to work out how to apply the Winged Temple of Orazca's ability: "Target creature you control gains flying and gets +X/+X until end of turn, where X is its power."
We're both quite new to MTG, so were wondering whether "where X is its power" meant:
- Power value printed on the creature card (aka Base Power); or,
- Power based on all combined effects currently applied to the creature.
We settled on Power based on all combined effects. But since then, I found out about the Layer System aka Interaction of continuous effects. If I'm reading this correctly, it says that +1/+1 Counters are applied after the +X/+X ability of Winged Temple of Orazca (because the ability would come under "Effects that modify power and/or toughness" in Layer 7c, whereas Counters are Layer 7d)...
Here's an example, listed by time of casting:
Creature Thrashing Brontodon 3 / 4 Aura Oakenform +3 / +3 Equipment Short Sword +1 / +1 Counters from Hadana's Climb 3 x (+1 / +1) Ability Winged Temple of Orazca +X / +X where X is power
So, if we assumed +X/+X is applied based on all combined effects, the Brontodon would be 10/11 at the point the Ability takes effect. So X would equal 10 and the Brontodon becomes 20/21.
But, if the Counters aren't applied until Layer 7d - and the Aura, Equipment and Ability are all in Layer 7c - then the Brontodon is 7/8 at the point the Ability takes effect. X equals 7 and the Brontodon becomes 14/15. Then the three +1/+1 Counters are applied and the Brontodon ends up as 17/18.
Is that a correct interpretation of the Layer System?
