You could always run Arc Trail / Arc Lightning package for splicer hate. Not sure if that just makes burn too good though (or if you even want to run hate cards - dividable burn hurts a lot of decks).
Hard for me to be objective on any of those cards.
Haakon - sort of a pet card. Early versions of my cube, you could run that in any discard deck and it's a standalone value/threat due to the recursion. Without exile, it never goes away and you can just keep casting it. Works really well with Stax type decks or any high removal strategy. Wrath the board, recast Haakon. He is pure CA as long as the body stays relevant. As creatures have gotten more powerful stat-wise and do more with they ETB, this card has needed the Nameless Inversion combo aspect to remain draftable. You may or may not need that component depending on where your power level settles. I've never once coupled him with knights though. That part is flavor text as far as I'm concerned. His value is in being castable from the yard.
Reveillak - another pet card. This one pretty high power. My favorite play is combining with Karmic Guide. But it's fine as a top end for aggro-midrangy type Wx decks to just repopulate the board after a wipe. Is it a value card? Definitely. Boring? I don't think so at all. Getting back two 2 power dudes for 6 mana is somewhat at odds. If you are running a bunch of weenies, how are you getting to 6 mana? If you get to 6 mana routinely, don't you have better things to do than get back a couple 2/x dudes? So it feels like you have to build around the effect or you wind up with inefficient value. It's a very strong card and some meta's shouldn't run it, but of all the ETB abusive cards, this is the one I think is the coolest and most interesting.
Sun Titan - sigh... I have been against Titans from pretty early on. They were in one of my earliest builds. Grave Titan ruined some games. Later on, I tried testing Inferno Titan and it proceeded to ruin games. Frost Titan is the one I actually almost put back in a later version of my cube, but in testing it was too effective and was impossible to remove. Sun Titan though? I don't know if I've ever seen it really in action to make a fair assessment. But guilt by association. I think the package you get for 6 mana on all the Titans is just too much value. But I'll freely admit I have a hard time being objective about any of those cards, so I could very well be off here. It's like asking me about Planeswalkers. I ran the original 5 in decks and can speak to what they can do, but I have not played with or against any printed after that so I really don't know what I'm talking about.
