WotC's stand is that they don't tend to do multicolored cards that could be mono-colored. This looks very mono- to me. White feels somewhat wrong here personally as I dislike the concept of having access to artifact removal. Making target player sac stuff isn't particularly either so it IMO doesn't work from that angle either.

The official stance sure contains the word "try" (or "tend" as you phrase it).

You might not be aware, but you actually are just pointing out the cycle's theme to me. It's five commons that could be monocolored in their main color but are slanted towards the supporting colors.

This particular card makes some assumptions that are no longer reasonable from the direction the color pie has advanced though, so it requires a little refresher to make white more pronounced the same way blue and black are in Tidehollow Gargoyle.

Making player's sac stuff is fine by Tribute to the Wild, but that shouldn't be the issue here anyway, because the sacrifice angle of this card actually comes from main color red (Misguided Rage) - it's the aspect that gives up control over choosing affected permanents to the target.

I'm open to constructive suggestions for an improved text, though I'll likely pick ideas apart a little and mull them over before settling on a replacement. :)
