Sentinels of the Bloggerverse - Tachyon Deck Guide

Uh, I think you might be overselling Lightspeed Barrage a bit. It's a good card, don't get me wrong, but you have your examples buffed with a +13 and a +21 Critical Multiplier. At best,  there can be only 19 burst cards in Tachyon's trash.

Synaptic Interruption can also be used offensively, by targeting herself. Combined with Sonic Vortex, you can deal 6 damage to a single villain. Nice to have a big attack that doesn't use up Lightspeed Barrage. Since, it also sends a Burst to the trash, it doesn't use up one of Sonic Vortex's targets. You could do the same thing by targeting yourself with Lightspeed Barrage for one more damage, but sitiations where that matters doesn't come up too often.

3 points in regards to Super Scientific Tachyon. 1) She doesn't have to target hero decks. Sometimes, it might be better to target another deck. 2) She combos nicely with characters that can stack the bottom of a deck). 3) "It can enable more plays, which is great, or it can be a total bummer if it doesn’t work." Not such a total bummer if you want cards in the trash, for example, by targeting Tachyon and getting bursts cards in the trash. You actually mention this point in Tachy comboing with Visionary. While you would usually prefer to have them played, there is some benefit. Also, characters that can pull cards out of their trash, might benefit from more cards in the trash.

Don't forget Luminary!  Luminary LOVES things being in his/her trash!

For Super Scientific Tachyon Experiments stats you can go here https://www.handelabra.com/blog/2014/12/19/super-scientific-experimentation which has all the decks through VotM for heroes, villains, and environments.  You mention F5 Tachyon eating into Lightspeed Barrage but never mention it can be used in conjunction with it.   Hit with a big Lightspeed Barrage and then use the power to hit an enemy for that same amount.  Lastly, F5 Tachyon Can combo well with Rogue Agent KNYFE or Fugue State Parse to keep replaying a Fleet of Foot or any other card she has multiple times over the game. 

Glad the BLITZ Tachyon got more love than in the initial draft. Wholly reliant upon buffs to make an impact, but it's nice to have an option for turning Tachyon from a Support character into a Bruiser without having to wait the whole game to launch a few high damage attacks.

I don't play Tachyon much, partly because so many other friends I play with all jump to her. It's a bit ironic that the speed-themed character takes a long time to wind up for her big attack.

In a way, Super-Scientific Tachyon's experiments never fail when she experiments on herself. She either plays cards (which is awesome) or ends up with more cards in her trash (usually one Burst, which is better than Rapid Recon can do).

As long as you're calling out Team Leader Tachyon/Guise combos, it's worth noting that Guise's Infinite Sellout (essentially, trigger Sellout, play Best Card Ever, redraw combo pieces with Where Did I Leave That, destroy Selling Out with Retcon, replay Selling Out with Retcon, you're still at the end of the environment phase, repeat) combo usually relies on him having his whole deck in hand, so her multiple sources of card draw can really help him.

Sucker Punch is better than 0/5 in some MUs - particularly against Voss with Gene Bound guard in play or the Chairman with Crooked Cops in play, her smattering of low damage hits can sometimes struggle to find targets.  It's also right-sized to kill the Informant in a single hit, the Informant is simply the worst, and Tachyon is usually a great first-position character (ongoing and environment removal, everyone else wants their additional cards before their turn), so if your Sonic Vortex isn't available or burst-enabled yet Sucker Punch is good from the word go. It also has a *very* niche use in letting Tachyon nab Death-Caller from Kaargra, which is a fun upgrade to her AoEs.  So while it's certainly Quick Insight discard fodder in most cases, it's not strictly useless.

Nimble Strike can be a preferred play in certain team lineups - 1 damage to 1 target is bad if you're trying to hurt someone a lot, but if you have allies you who have effects that trigger off being damaged it's a good way to do it.  For example - punch Dynamic Siphon attached to Argent Adept, or a fully kitted out Dr Medico with an Upgraded Memory Benchmark on the team.  Or just punch Cryo Bot, he's expecting it anyways.  It also is a perfectly fine tool to use when you know you have a high value top card of your deck in hand (e.g. you've Reclaimed from the Deep/Vernal Sonataed/Don't Dismiss Anything-ed Fleet of Foot to the top of your deck) and you have one+ of Tachyon's options for playing more than one card in a round going.  Finally, if you're stacking damage buffs, sometimes all you're looking for is "this card does any damage at all" to unload the rest, and you might as well get a card draw out of it.
