You know what else if funny. I've been going back and forth to see what deals I can find, but not really sure which deal to settle on. I would buy a house for 25% off, but not even sure who's I'd want. So far, I've gotten offers on houses for Autumn Stump Smash, Fireworks Zook, Crusher, and Whisper Elf, plus houses for Eye Brawl, Buddy Wrecking Ball and Ninjini (all of which I already had). I can't afford them all, and I want to save some gems in case they have a timed quest for Snowler Brawl's house or Quickdraw Rattle Shake. Which houses are you looking for and why?
Referring back to another thread on the subject, if I had to choose houses I'd start this way (assuming gigantus and #1 fans are owned):
if you still need gold, then Tree Rex house so can use Barkley and keep Tree Rexes free for their 75% bonuses
Ninijini - use mini-jini and keep 2 giants free for 50% bonuses
Thumpbacks - use thumpling and keep 2 giants free for 50% bonuses
Eye-Brawl - use eye-small and keep giant free for 50% bonus
Hot head - only giant/alt/legendary house I know of that gives 8 gems
After that, to me it's really a toss-up, but I'd go with alt/sidekick houses next because you're only giving up 25% bonus instead of the giants 50% bonus.
If gold is no longer a challenge for you, then I don't think it really matters and I'd get Hot Head because of the slightly better gem production.
