I think [Garuda] is currently the single strongest Warframe in the game.
Seeking [Talons] (with [Blending Talons]) primes all enemies in a 25m radius to take slash procs on any subsequent damage.
She has infinite energy between Bloodletting and Molt Reconstruct, and Bloodletting fills a percentage of your energy pool, rather than a flat amount. Nourish increases the energy you receive from bloodletting to compensate for negative efficiency and adds viral damage to all damage you do, including the charged 1.
She has a couple temporary invulnerability states (casting 4 and 1) for when you get shield gated, and long term directional invulnerability after casting 1.
Her charged 1 is a large AoE nuke which ignores obstacles, and, as long as you have cast 4 before the charged 1, will slash proc all enemies around you, amplifying the nuke damage you threw.

She is not weapon dependent at all, ignores armor through slash procs and does the same things across all factions. Her random invulnerabilities provide all the tank necessary. She is never a bad choice to play, other than trivializing virtually all gameplay.

Swift momentum is used mostly for squad melee combo duration, but is mostly a filler slot. Forma out/in whatever you desire, but she doesn't need Corrosive Projection or Energy Siphon.

For Archon Shards and moving to full minmax Tauforged: I would recommend 1-2 Casting Speed, then fill the rest with Energy Max Shards, remove [Primed Flow], slide [Stretch] into its spot and drop [Dread Ward] (the [Dread] Mirror augment) in. Because 12.4 seconds of refreshable invulnerability on top of everything else just sounds ludicrous.

Alternate configuration to use Gloom instead of Nourish, but I've found Nourish to be much more fun.
