If your auras or equipment cards are swept off the battlefield, Tiana can bring them back to your hand at the next end step so you can start rebuilding
I want to discuss the remaining cards that change a players maximum hand size together, mostly because they all see play in EDH/Commander
When you know your opponent has the removal in hand, it is sometimes better to draw by tapping 3 merfolks than dealing 4 dammages with two 2/2 creatures because the third have summoning sickness
Use the binders just as you would in real life to organize and to show off your cards
If you do so, you will first put three +1/+1 counters on that creature, then remove all +1/+1 counters from it, then draw that many cards
That still holds true of Commander, though you see the card way less frequently now
