Ugh , excuse me , but it ' s Tiny Rick , biitch ! .<| sep |> Ah , thanks for informing me . So the deck he uses is illegal in the metas , but is it legal in paper ? It is illegal on MTGO , and legal in that particular paper environment . If so , does desert make teachings a viable deck ? How important Desert is remains to be seen . One 1 st place finish is an interesting data point , but it doesn ' t mean the archetype is now tier 1 Remember the BG Sacrifice deck that won in Argentina ? That never really panned out . .

If it appeals to you , try it .
