the other cards seem limited of use - but reasonably costed for what the do (eg seismic spike couldn't really cost any less) but I would have reservations playing barreling attack in limited if it cost so my vote goes there
Gate hound with HM's to infectious host and light of sanction Honestly people, do you just pick the first card alphabetically instead of looking at the options - benevolent ancestor is nowhere near the worst card here (I'd say that there are 5-8 cards less playable)
there are a lot of narrow cards at this cost - no truly overcosted or awful - so I'll follow the herd and go for part the veil as I can see no real use for it at all at this cost - ghostway does the job MUCH, much better.
This card is ridiculously powerful - a 2 power creature for 0 mana in any colour of deck? the card reminds me of vine dryad - and that saw legacy play just because of the freeness. A nice card, but WAAAY too powerful to ever be printed. for a non-broken version of this card, see skyshroud cutter
lifegift sucks, but can gain more life over time than wandering stream, and multiple events will trigger stuff like searing meditation - so my vote goes to the stream
"Wrath?" "SCOOP!"
