Since Morskas ability triggers every time you draw your second card each turn not just your own you can sacrifice Clues during your opponents end steps
Youre constantly one step ahead, setting up combos that swing the momentum of the game, just like in some of the best trading card games that reward clever planning and energy management
Spoils of Victory from Portal Three Kingdoms (1999) is again a less efficient card, but the wording, which doesnt mention basics in any way enables better color fixing through getting any of the original duals or, later, shocklands or battle lands
It's indestructible and extremely impactful for four mana, compared to something like The Endstone
Think Angel of the Ruins, Krosan Tusker, Striped Riverwinder, and Shefet Monitor
That copy costs less to cast
