So basically the deck is just about Dinosaurs, though there's a bit of an Enrage subtheme too
1000+ mtg cards (common, uncommon) from a variety of sets, some duplication, little to no basic land.
A deck that focuses on ramping up mana quickly, such as a green ramp deck, would benefit from using Explore as it allows for playing an additional land and drawing a card in the same turn, providing both card advantage and mana acceleration
It has always been rather a clumsy card whose abilities rather counter certain different things rather than offering any particular synergy with your own strategies
Its big value, but honestly no reason for this card to be banned
The deck managed a 5-0 finish in yesterdays MTGO Pauper League, so its doing well right out of the gate
