MTG Salvation

I would go a bit more control then - Not "counterspell" control, or try to control the whole board - but rather the "Discourage people from attacking me". When we had a period of big creatures at my meta, it was brought a bit down by a lot of boardwipes, and a few highly resilient creatures (indestructible/Persist/etc) with some extraneous equipment to make a few decent creatures into acceptable threats.

Keep creatures back, and removal spells in hand. Don't be the biggest threat, so people don't feel like they NEED to hit you, and don't be the lowest threat, so that people think they can get free shots off on you (thus, forcing you to actually USE your removal). The final piece of this is to ensure a decent amount of recursion, or ways to rebuild your threats quickly when wipes occur. For example, a slight Equipment theme (you don't need to go full on), can turn any mediocre creature into a decent enough threat. Vehicles provide an outlet of larger creatures that more easily survive most wraths, and can swing back immediately for a punishing crackback.

I tend to like Green/White for this, myself. From the Commanders you've listed, I like Anafenza, the Foremost the most. Both Anafenza and Dromoka encourage you to attack, which is a bit the opposite of what you want to do (it makes you a target), but Anafenza has utility even if you just need to chill back. Anafenza can also dump counters onto guys that got tapped for reasons other than attacking, and an early game 4/4 will provide more deflection early on.

It sounds like you have a limited card pool, so the addition of another color will let you reach more broadly and select better options across the line, and black adds some good deathtouch rattlers that have good utility as well.

The roles for your colors here (although if you have good cards that cross these, go for it!) will generally be:

• Green - Ramp, and the big resilient creatures to threaten. Mass survivability. Card Draw.
• White - Removal, Removal, more Removal. Also some recursion and big creatures. Vigilance is highly underrated. It lets you poke in, but still keep up your defensive formation.
• Black - Recursion, Rattlesnakes, and removal. Card draw.

Some of the cards that would fit well into this style (these are jsut examples, I don't know what you own, or how they can fit into your budget:)

Removal:

• Swords to Plowshares, Path to Exile, Tragic Slip, Necrotic Wound - One mana removal spells. These let you keep up little mana, so you can develop on your turn, but still let you react if something bigger than your defenses comes barreling through.
• Soul Snare - Sometimes the THREAT of action is stronger than the action itself. Soul Snare can help deter larger creatures from coming your way. This can bite you back though, as if you have insufficient defenses, people may throw their weaker creatures, like Solemn Simulacrum at you, in order to try and get you to 'waste' the snare.
• Rout - As an instant speed board clear, Rout hits in my top 3 favorite wraths of all time. Angel of the Dire Hour and Fated Retribution can also fit this style, though are more limited.
• Wing Shards - People learn to respect this card very quickly.
• Beast Within, Generous Gift - Don't forget removal for things other than creatures as well. These are great catch-alls.

Recursion:

• Sun Titan - Gold Standard of white staple card - this functions as a beatstick, recursion, the Vigilance is great, and it can even be ramp.
• Emeria Shepherd - This is an insane recursion engine, tempered only by the fact that she makes you an immediate threat.
• Undying Evil, Supernatural Stamina, Thrilling Encore - These little combat tricks provide excellent surprises. The one cost one shots also work great with Burnished Hart.
• Kaya's Ghostform, Gift of Immortality - works great to protect what you want late game, and early game are fantastic to toss onto a Burnished Hart, Farhaven Elf, or any other ramp/draw creature.
• Eternal Witness - Another staple of Commander.

Rattlesnakes

• Glissa, the Traitor - Firststrike and Deathtouch are potent together, but Glissa can be a huge target as she can be quite crazy if built around. Adds a touch of recursion for you.
• Knight of the Ebon Legion - Can be a potent blocker, and can work well with equipment later in the game.
• Rhonas the Indomitable - Survives wraths, pairs will with the commander.
• Skullwinder - Budget Eternal Witness.
• Vampire Nighthawk - Original. Solid. Flies, the lifelink pairs well with equipment later.

You'll probably want a few decent fogs here as well, just incase a surprise Craterhoof infused horde comes your way:

• Spore Cloud, Tangle - Both great, as they really punish the attacker by giving everyone two turns to smack them back for it.
• Moment's Peace - Two uses is always great.
• Batwing Brume - Lovely to toss into a token swarm.

Generally, your goal is to deflect people to other opponents, and try to maneuver yourself into a position to take advantage of that and clean up at the end with better resilience and better removal, or, simply MORE of both (even if not better) due to the fact that you haven't needed to use it it - the threat of using it being enough to send people in other directions so you don't have to expend it.
