Gargos, Vicious Watcher rulings

2019-07-12
To determine the total cost of a spell, start with the mana cost or alternative cost you're paying, add any cost increases, then apply any cost reductions (such as that of Gargos). The mana value of the spell remains unchanged, no matter what the total cost to cast it was.
2019-07-12
Gargos's cost-reduction ability affects only generic mana in a Hydra's cost. For example, if you cast a Hydra spell with mana cost , it will cost to cast, not .
2019-07-12
If a spell has in its mana cost, you choose the value for X before applying cost reductions. For example, if you cast a Hydra spell with mana cost and choose for X to be 6, you pay . Any of that Hydra's abilities that refer to X still uses 6 as the value for X regardless of what you actually paid.
2019-07-12
Gargos's cost-reduction ability applies only while it's on the battlefield. Gargos doesn't reduce its own cost.
2019-07-12
Gargos's controller chooses which creature (if any) Gargos will fight, not the controller of the spell.
2019-07-12
If a spell targets one creature you control multiple times, Gargos's ability triggers once. If that spell targets multiple creatures you control, Gargos's ability triggers once for each of those creatures.
2019-07-12
Gargos's triggered ability resolves before the spell that caused it to trigger. It resolves even if that spell is countered.
2019-07-12
If the target creature is an illegal target when Gargos's last ability tries to resolve, the ability doesn't resolve. If Gargos is no longer on the battlefield, the target creature won't deal or be dealt damage.

Gargos, Vicious Watcher keyword rules

Vigilance Rule 702.20

Vigilance is a static ability that modifies the rules for the declare attackers step.

Attacking doesn’t cause creatures with vigilance to tap. (See rule , “Declare Attackers Step.”)

Multiple instances of vigilance on the same creature are redundant.

A spell or ability may instruct a creature to fight another creature or it may instruct two creatures to fight each other. Each of those creatures deals damage equal to its power to the other creature.

If one or both creatures instructed to fight are no longer on the battlefield or are no longer creatures, neither of them fights or deals damage. If one or both creatures are illegal targets for a resolving spell or ability that instructs them to fight, neither of them fights or deals damage.

If a creature fights itself, it deals damage to itself equal to twice its power.

The damage dealt when a creature fights isn’t combat damage.
