Elder Gargaroth : A newer Wilds of Eldraine entry, this card is a creature that will allow you to draw a card whenever you cast a creature with an Adventure
The goal was to self-bounce and recast your things to trigger ETB things (Mulldrifter), self-bounce things (Azorius Aethermage), leaves play things (Circuit Mender), cast things (Equilibrium) and tapping the dork for something valuable (Opposition), with a bounce of self-bounce (Erratic Portal) and a flicker backup theme (Far Traveler proper) in order to lean into the non-cast stuff
At the time of the announcement (see here), there were mixed feelings among the community, in particular in relation to the impact the decision would have had on the meta and the competitive events
Before we get to that, though, theres a few things to mention
The game plan is fairly simple, get ahead with your cheap early ramp, cheap disruption and over sized cheap dorks
