It's worth noting, though, that Show and Tell can be a bit of a trap in league play because your opponent could be on a similar deck, resulting in the card backfiring on you
For example, the most powerful draws that Elves in Modern has involve going off on turn 2 with Heritage Druid and Nettle Sentinel and playing most of your creatures, but in practice Nettle Sentinel is among the worst creatures in the deck, and its better to trim them rather than the less exciting but more consistent mana creatures, Llanowar Elves and Elvish Mystic
When Amonkhet even gave us a cycle of lands that cycle (ba-zing!), its pretty hard to reasonably justify cheating on ones land count
Most instances of explore are found on creature cards, but MTG designers often find clever ways to get the most out of a mechanic, so youll see sorceries that let creatures explore, or vehicles that make the creature crewing them explore
