I am not so sure about the minion changes. Sandhowler seems broken with whispers of the sands which cycles itself already.
At the moment I am against stronger Vetruvian minions until Inner Oasis gets reworked to not be a win more card.
The wind slicer change honestly is very interesting. Definitely will spark deck building on my part if it goes through. Can’t stress it enough how interesting it is.
Orb Weaver change I am not so sure honestly. Sounds too snowbally for my taste.
I wonder if reworking it into a support unit that does what it currently does but heals friendly characters around it at the end of the turn might be interesting.
Fountain of Youth change seems good. However I would advice that it is a health restore instead of damage prevention for the sake of keeping the health restore flavor. Otherwise I like the proposed change.
Sandtrap rework I find while interesting, I personally would like to see sandtrap tweaked instead of reworked into a different spell. The way I view sandtrap, is that it is the counter-part to the “nearby to your general” cards. While dominate will is good, entropic decay is meh, and new siphon makes purify look good. Sandtrap in of itself just needs a small tweak for it to be competive and it is added to the other cat&mouse cards Vetruvian has i.e. “Do I play around blast or dancing blades/star’s fury?”.
A one mana sandtrap or a sandtrap that cycles itself would be rather good buffs to the card. Not sure which one is better for the card.
Would love to see how someone reaches this conclusion though!
Otherwise I probably wouldn’t have replied.
