Board clear, but you would be pretty desperate to use 8 mana on a card that is not certain to kill everything.
Short answer, yes. Basically it costs too much mana for 5 damage AoE in faction that can do burst damage for more with less mana. Also has better removals in the form of Natural selection, Plasma Storm and Egg Morph which are all cheaper. Plus Warbeast costs 2 mana less and can do 4 AoE damage which can be ramped out earlier (if needed).
Flavour. Its suppose to be like a late game AoE that helps out the rebirth archetype. But in reality it is basically unplayable outside of just wanting to use the card because you own a copy. Costs too much mana, rarity is too high for people who would want to test/use it, the AoE 5 damage isn’t that impressive for 8 mana, plus you’ll be killing your own minions or putting into egg form which makes it easier to your opponent to kill them.
Pretty normal, don’t really celebrate it, although it does mean there could be Easter eggs for sale tomorrow which is a nice way to get chocolate on the cheap with maybe a free mug. Also don’t think I’ve ever been Easter egg hunting.
