In my current build, cards like this don't make the cut, but if I were to build a different version (maybe a budget one?), it's very attractive as a large creature that can be played for a low cost
Black Lotus can help you cast a high-cost win condition and Shivan Dragon can save you if you need a flying creature on the battlefield to stave off an opponents horde of flyers
Cards from every set (except ones with a silver border or an acorn symbol) are legal in the format, making nearly every Magic card ever released allowed to be played
You'll still need one copy of the Outlaws of Thunder Junction printing to be able to use that visualization, but once you have that single copy in your collection, the game will treat it as though you had four copies of the card from the preconstructed deck
Fake chase cards like full art trainers and EX, GX, and V/VMAX cards will often have a slightly reflective back in addition to their reflective fronts
Additionally, unlike The Ur-Dragon and Edgar Markov, you need to pay mana into Inallas effect to make use of it
