Being able to hold up Rift on your opponents' turns to cast at any time, or just spend the mana to do other things, is huge
Plus, Ygra gets much stronger when you cast your board wipe, gaining two +1/+1 counters for each food that goes to a graveyard
What was already a respectable pile of counters suddenly becomes enough to create a truly absurd number of Insect tokens for only three mana
It's a slow and roundabout way to establish a board presence, but now you have two 5/5 creatures
Put it in a token deck, and itll fly (pun intended), and I think theres scope to sneak it into an Aristocrats-style deck to get some aerial firepower, but overall I think it deserves fourth spot here
All three are probably familiar to players in some form, with Thrasios, Triton Hero and Vial Smasher the Fierce likely being the most iconic pair to come out of this product
