Soooo, is this is looking like another 4* DDQ I’m not going to be able to complete?
My Electra is 160 1/4/4 & neither red nor black power damage seems like it’s going to be enough to take Blade down? Red trap tile just gets overwritten by Blade’s strike tiles as soon as it’s out & black trap tiles neither do enough damage or last long enough.
This just looks like another 4* DDQ which is a waste of time attempting - even though Electra is my 4th highest-covered 4* after XF, Fury, & Ant Man.
2/0/0 here, waving the white flag after 1 attempt. 
I’ve come to accept this is a part of the game that I am not welcome to participate in.
You can defeat him. I got on my second attempt and without booster. The secret is to get purple and black before the Blade. If you’re not lucky, like me, I recommend using some purple and black booster to accelerate the process. Use the purple once you have at least 2 strikes the Blade. Only use Shadow Step when Blade is loose black or purple power. If you use shadow step as soon as you get probably should come down because her purple is weak. If he shoot Black power are 3k damage and purple are 3k per round.
I got it on 2nd try with 167 1/4/4. I felt pretty hopeless after the first try, but it is doable if you get a good board. I agree that getting purple and black before Blade does is key. I did use boosts, but was able to get purple off 3 times and then black did a fair deal of damage towards the end (he basically ended up killing himself when he used night tstalker on me).
Got myself 
My Elektra is lvl 168 with 3/2/3 and I beat him on 3rd attempt.
Yes you have to deny purple first so that you can use them against his strike tiles, then deny black and then red in that order. Once he gets some strikes out see if you can match them away and if not double cross him.
Only do ballet of death when there are less than 6 red and they’re not close together. Also do the same with shadow step and cast it when the black tiles are far apart. Soon the combination of ballet, step and double all add up and he melts away into the shadow.
Ok cool, I’ll persevere then - I’ve kept dying from match damage with boards flooded with red so far.
Aaaaaaaaaaaaaand, a couple of extra levels and lucky board later & we’re done.
Got a 
for my troubles - which is at least better than pulling another 
XF token to go with my fully covered one like I did when it was his turn on DDQ
1/1/1 Level 78 Electra.
Guessing there’s no point in even opening the node.
DBC
Completed with a fully covered but just level 140 Elektra. Took four tries, used 100% match damage, 50% green/black damage, and +2 G/B AP.
As everyone else said, target down black/purple, unless there’s a ton of red, in which case get red under the Thirst threshold, then black/purple. Hold your black traps until he gets enough black otherwise match damage will take them away before you really need them.
Whoa thank you all!! I had totally given up on this node with my 1/3/1 Elektra until I saw this thread.
By following y’all’s advice I got me my Legendary token on my second try!!
(Another Elektra, natch … now at 2/3/1)
Lucky board, and yes boosted +2 G/B, +50% G/B, +100% All. But still, success!
(wheeeee)
You guys rock. Won on 3rd or 4th try with level 111 1,2,2 powers.
The board I got wasn’t great, but you actually want Blade to attack with red so you can use purple to swap that out, with blacks to stay alive, and red to add to your damage after a purple swap. I think I attacked with purple 2-3 times, black 3 times, and red 3 times before finally winning. Took a ton of moves. I probably used Black here earlier than suggested just to remain in the fight.
feel like a rockstar did it with a 1/1/2 used 5x match damage boosters, 5x crit damage, and green black ap boost. Third try
Got a lucky 7 black crit tile early stole one 
from him and then got 2 red off that lasted the entire round. Denied him purple. He did his purple on the last turn (thankfully right after i dropped a shadow step) last turn was me with 664 hp and blade with 71. BOOM
got a 
for my troubles
Took me five tries with my 1/1/5 capped Elektra (I forget the level at the moment) and damage boosts (all, blue/purple, black/green). On the final try, I was able to get Ballet of Death out early and protect it, and managed to also deny purple and black, which I was unable to do on previous attempts because the board was full of those colors.
I let out a cheer as Blade went down, claimed my token, and proceeded to pull…my sixth red Elektra. D’ohhh!!!
My lvl 131 is 2/1/3…took me 9 tries and all my sanity. finally got good board (which seems to be key if ur not high lvl) and won with like 500 life left. Was pretty low on boosts by my 9th try, but used +2 all, +2 G/B, +2 PB. Got Thing
