1. What is your general opinion of Ike as a character?
Frighteningly strong, but has limited safe approaches vs. Link. When I come across an Ike player I am "cautiously optimistic". I always try to remember that no matter how much I am winning by, the game is not over until final stock is done. One missed spot dodge on a Fsmash evens things up real quick.
2. What moves do you fear from Ike?
With the caveat that every one of Ike's moves can be dangerous if used properly, the ones that I keep an eye out for are:
A. Fsmash. It rarely connects, but when it does Link does not have the recovery to make it back, even at mid-lower percents.
B. Bair. Deceptivley fast, huge knockback.
C. Jab combo. Waaaay too much damage and knockback for a move that fast.
D. SH Nair. Fast, good priority, sets up for Utilt/SH Uair's.
E. Usmash. Covers his entire body, reaches really far behind, hurts.
F. Fair. Not because it is incredibly good, but it is the one most commonly used to approach.
3. Which moves do not trouble you at all?
A. Counter/DownB. Comes out too slowly to be much use, and won't help much against projectiles.
B. Dtilt/Dsmash. Limited range makes them none too useful.
C. Neutral B. Again, no range. I'm going to be running away from him for most of the match.
D. SideB. Punishable, and I will usually have a projectile in between me and him anyway.
4. Which moves/techniques do you use against Ike to gain the advantage?
Depends on the other player. Generally I will try to force an approach and play spacing games for as long as I can. When he gets close, I try to bait a punishable attack so I can gain some distance again. Favorite tactics include:
Spacing games:
-SH forwards/backwards, bomb, quikdraw
-FH forwards/backwards, boomerang, quickdraw
-FH arrow, quickdraw
-Boomerang (tossed upwards) into charged arrow
-SH forwards/Backwards, Zair, into dash, into uair/utilts as much as possible
-Ike is slow enough in the air that I can often predict his landing and hit him with a dash grab during the 4 frames of landing lag. Do this constantly and it gets predictable, but as a mix up/mindgame, it can be effective.
If he manages to close to me, favorite tactics include:
Distance finders:
-Jab combo
-Jabx2 cancled into utilt into uair, etc
-Jabx2 canceled into grab
-SH Nair into utilt into uair, etc
-Up B out of sheild/spotdodge
-Charged Dsmash to counter rolling approaches
5. What specific edgeguards do you employ versus Ike?
If he is coming in low to use Aether for recovery:
-A SH bomb drop over the side can spike him against the stage, unless he times it miraculously to land on the super armor frames.
-SH Dair can catch him unawares, but timing to miss the sword and hit him as he rises is hard.
-Tap him with the tail end of the gale boomerang and it will push him back an inch or so, but give him no heght to work with. Sometimes it's enough.
If he is charging Side for recovery:
-A simple walk off edgehog can doom him, if timed just right.
-Jump off the side to get in between him and the stage, airdodge. It makes him attack and short it.
-If you have time, a charged arrow messes this one up pretty badly.
-SH Dair hurts this one a lot.
Ike can go either way, but I tend to feel like the game is mine to lose. If I mess up, I'll lose, if I don't, I'll win.
Ike is slow and tall enough that all of Link's projectiles are viable to use, as well as repeated Zairs as a spacing/mindgame tool. I tend to spend most the the match shorthopping with projectiles one way or another, trying to stay outside his range and bait a punishable approach.
If I start getting predictable with this, I'll go crazy offensive for a few moves, forgoing all projectiles, just to put some pressure on him, then go back to poking.
Hope this helps.
