Playing Magic: The Gathering can be exciting and varied
Just remember that whichever mode you choose to cast becomes the mana value of the card on the stack and on the battlefield, unlike other, similar built-in cost reduction mechanics like Suspend or Miracle, s o a commander like Yuriko, the Tigers Shadow very much likes Prototype cards, while Vial Smasher the Fierce does not
Mixing these two makes comparisons easily skewed
The same can be said of Felidar Sovereign, a creature that requires you to have 40 or more life on your upkeep to win
(We just had to remember not to make a Wall of Bricks in the set.) While Limited Edition (Alpha) , destroying a Wall is a little bit narrow these days to build a whole card around
Knowing theres at least one player at the table willing to help out other players can be nice in games where you arent doing so well
