Gains you 2, accellerates you 1.
Are we?
I feel like I would only cube this card if I had some sort of strange theme it contributed to or if I was already playing every rampant growth and fertile ground that cost less than it.
Because self-mill represents an alternate (and generally less efficient) form of card advantage, it can be outcompeted by more efficient draw spells, which can marginalize your self-mill cards. If people arn't playing self-mill as a way to get through their deck, than it becomes harder, but not impossible to justify spider spawning (or any of these cards really): it can always go into a generic G/x beats deck as a way to take advantage of naturally dead creatures in your yard. However, if your power level is high enough where a G/x beats deck can draft a more direct late game, its a low pick there as well.
Since both splinterfright and boneyard wurm require something be in the yard to even cast, those cards require some sort of cheap self-mill to even be viable. Splinterfright is a bit more justifiable, it can always come down as a late game 4/4 or 5/5 trampler for three, and powers itself; but boneyard wurm is likely to be a rather clunky and overly narrow threat. Splinterfright I would rank a mid-tier threat over here.
Skaab ruinator can be difficult to cast at times for us, and I have a lot of self mill.
Flashback cards are a strong self-mill reward, and operate across a broad power spectrum.
Looking forward to seeing the new cards. This is a really good portion of the magic card pool to design custom cards for i.m.o
As someone who runs Vendetta, Spite seems a-ok! I really like Grim Affliction, too.
Riverwheel Master feels really pushed - being able to disable multiple blockers isn't even something red gets to do easily on a body, let alone blue. Maybe if the controller has to pay ? I can imagine having this trigger on your opponent's combat step, and they effectively lose the ability to attack and block.
Roar of the Lion seems pretty sweet. I don't know that it's better than Travel Preparations, especially with the high flashback cost, but I suppose you might be running a lot of planeswalkers.
I love the art you've found for those cards!
That feels a little on the heavy side, yeah. What percentage of spot removal and mass removal are you at in your cube now? I would count things like Unexpectedly Absent and even Gideon Jura as removal, too.
Also, are you at roughly 48 to 50% creature count overall? If you're significantly lower than those numbers, it might be contributing to your creature density issue.
edit: Looking at your CubeTutor, it feels like your creature count is on the low side. White and green work better in my experience when they're north of of 60% creatures, especially green, which I usually have at 2/3 creatures. Red and black could both use a little nudge towards more bodies, too.
My approach is to keep staple effects (like removal) more scarce so that people will compete over it and use the space to have more situational cards (which people don't necessarily compete over, but instead need diversity). If some guy is just drafting 20+ removal cards like he hit the jackpot in a late 90's core set draft, removal is probably not scarce enough. Your removal set has a pretty significant power curve: what effects do you think this has? Is it interesting to pick between a bolt and a better threat, knowing that if you pick the threat you can probably grab a hammer later?
