First, I cant speak about the price of the new-to-Magic cards, because Im still working with unrealistically high presale prices at the time of writing
Kindred Discovery If you asked me what I thought the best typal support card was, Id happily say Kindred Discovery, at least for Commander
+1: Draw two cards
Team Tactics Its totally possible that Team Tactics sees play in current Standard
Been a while since we slapped our greasy little mitts onto this bad boy huh
Wizards pulled this off perfectly, giving us 900, 700, and 300 serialized versions of the same card (again with different art, and with the non-serialized, nonfoils still a difficult pull) they gave us the first 1 of 1 card in Magics history, opened by a player in Canada and famously sold to Post Malone for $2 million
