Lesson cards are actually back in Standard right now, appearing in Avatar: The Last Airbender
The deck is built around artifact synergies, ways to untap Shorikai for multiple activations, and control elements that let you grind out advantages while maintaining a powerful board presence
Various cards can add further power to the deck, such as the Goblin Anarchomancer, which makes green and red spells cheaper by one colourless mana, the Mage Slayer, which promises unblockable damage, or the Rhythm of the Wild enchantment, which protects your own creature spells from counterspells
One of the main considerations with a card like Permission Denied is that it can be difficult to hold up the necessary mana to cast it while still advancing your board
Treasure Chest is such a great D&D trope: will you find gold, or knowledge, or a relic of great power
The Spike As an uncommon card from MTG Foundations that didnt see a ton of play until recently, Bulk Up has surprisingly been rather cheap
