Play or Draw in Limited Frankly, a topic most players dont even spare a thought about anymore, where I think I am having a different take than most: More often than not, it makes total sense to get yourself that extra card that you deserve
But today, we can cheat this into play by blinking the morph, or with abilities from legends like Kaust, Eyes of the Glade or Yarus, Roar of the Old Gods
If you return four or more nontoken permanents you control this way, you may put a permanent card from your hand onto the battlefield
The exceptions are when a card has a golden border, as seen on Magic Golden Flower, and on action cards, like One Jump Ahead, where the card text takes effect immediately
It even works on-curve to cast TiamatTiamat on turn seven and an Elder Dragon on turn eight
That said, ability doubling is strong, regardless of what strategy you're aiming for, and many old ally cards have ETBs worth doubling with Katara in play
