I really like this card…
I’ve only drafted Magic Origins thrice, but somehow I’ve managed to draft this guy twice. I haven’t cast that many times. Actually only twice so far (in six matches), but any time I have, its been great. The two creatures I’ve been able to fetch with it are [scryfall]Elvish Visionary[/scryfall] and [scryfall]Yeva’s Forcemage[/scryfall]. Both have pretty good ETB abilites. The Forcemage was pretty meh the last time it was in a core set, but now, with all the creatures with renown and a fast format, its pretty good. Making Bellower a cantrip is good as well. And then there’s [scryfall]Shaman of the Pack[/scryfall], which can just end games.
In standard, Antonio del Moral Leon was playing a [scryfall]Demonic Pact[/scryfall] deck at Pro Tour Origins. Of course, the “Lose the game” -clause is very much unwanted, so you either have to win, destroy it, or return it to your hand before the final turn kicks in. For this purpose, he had (among other stuff) an [scryfall]Invasice Species[/scryfall], which can be fetched for with [scryfall]Woodland Bellower[/scryfall]. How cool is that? How good is [scryfall]Anafenza, the Foremost[/scryfall] going to be if those [scryfall]Rally the Ancestors[/scryfall] decks continue to be played?
Then there’s Commander. This card has EDH written all over it (although there might be some interesting combos in Standard to come). I’m guessing the grossest way to use it is to find either a [scryfall]Fierce Empath[/scryfall] or a [scryfall]Mwonvuli Beast Tracker[/scryfall] to search for another big monster. Fetching for a [scryfall]Eternal Witness[/scryfall] has pretty much the same value, depending on the situation.
There’s also plenty of ramping options, such as [scryfall]Farhaven Elf[/scryfall], [scryfall]Wood Elves[/scryfall] or [scryfall]Fertilid[/scryfall], not to mention all sorts of bullets, such as [scryfall]Scavenging Ooze[/scryfall], [scryfall]Reclamation Sage[/scryfall], [scryfall]Loaming Shaman[/scryfall], or [scryfall]Selkie Hedge-Mage[/scryfall].
I bet there’s more intricate ways of using it, but this is what I could come up with while writing this. I guess next step is figuring out how to flash it into play.
