MTG Salvation

I love cards like Deflecting Palm/Swat, Reins of Power, & Wild Ricochet.

I am considering building a commander deck around this theme.

What are a bunch of other really good ones? Color doesn't matter.

Words of Wisdom is a funny way to win against Oracle Consultation

The card example in the OP suggest decks that are often described as "You did this to yourself" or "aikido" decks.

Delirium is fantastic against massive creatures and Blightsteel Colossus.
Batwing Brume and Rakdos Charm are great against swarms.
Inkshield turns a massive attack to your advantage.
Taunt from the Rampart is great for turning the entire table against itself.

Other cards that turn a wincon against its controller include:
Tainted Remedy makes short work of lifegain decks. False Cure can do some damage if there's one big instance of lifegain.
Haunting Wind and Magnetic Mine against artifact/treasure decks.
Acidic Soil, Ankh of Mishra, Price of Progress, Polluted Bonds, Treacherous Terrain, Zo-Zu the Punisher all punish ramp decks.
Netherborn Phalanx also punishes swarms.
Narset's Reversal can stop/copy a winning spell.
Dismiss into Dream shuts down voltron decks and similar targeting decks.

And other punishment cards:
Ruric Thar, the Unbowed punishes noncreature decks.
Burning-Tree Shaman, Harsh Mentor, Immolation Shaman all punish activated ability decks.
