4-1-4 Rulk advice?

So I’m looking to get creative to champion my Rulk and I figured I’d ask for some advice here as I’ve been neglecting him because of his current spread (4-1-4). Currently, I have Thanos (168) and Thor (202) that each reward a Rulk, but one would give me RED and the other PURPLE (I need GREEN). The way I was going to approach it would be to do the following (in this order):

1: Start saving CP in case I need to “buy out” the GREEN for 125 CP
2: Favorite him now and hope for a bonus GREEN
3: Wait to favorite Thanos or Thor until Step 2 inevitably gives me a bonus PURPLE or RED
4: Favorite whichever one is left (i.e. if I get a bonus Rulk PURPLE, I would favorite the 3star that gives me bonus RED)

I assume that I would get a bonus GREEN before I got two REDs or PURPLEs. I’d hopefully get two, but just in case I’d have the 125 CP saved up. What do you think?

Go the Cp route. Save about 240 more.
set Rulk as bonus.

If you are in a rush, use all CP on covers.
If you aren’t in a rush? every other 120 go for 6 pulls.

Unfortunately that’s all you’ve got. He won’t be around in another PVE or PVP for about 30 or so more each IIRC?

The Vintage Heroic isn’t reliable at all.

Bonus heros can and likely will be the Rulk green lol. they can be anything
