Thanks Reymon. Can you elaborate on when you find Displacer useful and what it does for you? I've tried the card in a few leagues but I always seem to have better uses for that three mana, i.e. developing my own board or disrupting my opponent. Unless it's a really grindy game I don't seem to use the blink much.
Also, is two Relic enough to support your Stranglers?
I would say anyone using Disenchant in the side should try Fragmentize. I've never ran into an artifact or enchantment where the CMC restriction was an issue (fully realizing I just jinxed myself).
Of course, Displacer is in my main because he is good in basically any creature matchup and with TKS and Sculler sometimes even against combo.
Firstly it's a 3/3 creature you can play on turn 2 with Eldrazi Temple. Just that on it's own is very good.
You can apply pressure in the early game(without the ability being to relevant). You said you have better uses for your 3 mana, that's perfectly fine, do that! Displacers ability is there to use, when you have nothing better to do with your mana. It's good in the early and a long stalled grindy game.
Where Displacer has been good for me, it has won me the game several times: 1) against Death shadow I was on 3 life and had a knight of glory and displacer out. Combined with the discard I manage to control the whole game and deal with a gurmag angler and 7-12 power DS.
2) Against Mono white Death&Taxes and other random tokens(Voice for example), it is an all star. You blink their tokens and they're gone.
3) Against Jund I managed to play it and blink Wasteland Strangler 3 times to kill a Goyf + Kalitas.
4) I haven't got to do that yet but he's also great with Thoughtknots to control their draw step. He's also very good with Tidehollow sculler if you already processed the card exiled with it or it's an irrelevant card meanwhile.
5) As long as you have mana open, he acts like a spellskite, they have to kill him first even if they're threatened by a Smasher. If you're lucky enough to have both out it is game over.
6) Clear the way in a stalled game. Imagine you have 2 temples and 5 lands, the opponent has 6 creatures. They can't really attack you as you just block and blink in response. At the end of their turn you blink three blockers and on your first main phase you blink another 3, GG.
You will find other random situations where this card is just great. Opponent Spell quellers your Thought Knot Seer? No problem, blinking the spell queller they can't stack the abilities to counter your TKS again. Against Affinity they couldn't attack as I would always just blink the creature equipped with plating. It's also amazing to reset couters given by ravager.
Against Eldrazi Tron I flickered their Hangarback Walker, oh no it's a 0/0? Dead.
I could talk even longer but I will just recommend to play two^^
And two relics is enough like 80% of the time. Sometimes you have to play your TKS first but it usually doesn't matter. Worst case scenario you have a 3/2 creature. But when I have enough creatures i like to hold them.
Thanks for the detailed response Rey, you have me believing! Do you find the -2/-2 on Flaying Tendrils to be a problem? I ran that for a couple leagues and it wasn't able to sweep away elves once they have developed their board. I also can't recall the exact creatures but it might have problems sweeping creatures from CoCo. I've been using Wrath of God...not sure if it's better. Could Bontu's Last Reckoning be an option? Sure, your lands don't untap the next turn but if a red deck or elves have vomited out all their creatures and you wiped them so what?
It's true that Tendrils doesn't kill everything. I think it hits almost every important creature in Coco though, at least all parts of the combo. Resolving it against Elves before they have two lords is essential. If you want to play a hard wipe, I would play Damnation. I'm not a fan of Bontus last Reckoning at all. The not untap thing is pretty relevant.
I will stick with Tendrils I guess. The -2-2 is an advantage as it is a one sided board wipe sometimes. It doesn't kill our Eldrazi. I think the most important thing using Tendrils against e.g. Elves, Merfolk, Coco and other stuff is not to act greedy with it. I'll play it as soon as I can get a 2 for 1 out of it. Even killing some dorks against Coco or killing a heritage druid and Mana elf is more than enough to gain huge tempo.
