Now that Ive got that out of the way, Ill take you through my logic in more depth
When youre able to attack with Etali, all bets are off because getting up to two valuable spells that you are able to cast immediately without paying their mana costs, not just draw the spells but cast them right away, is incredibly valuable and has the potential of taking over almost any game
Because they cant do anything at all with that mana during your turn, it guarantees that all of your opponents will be losing 3 life each turn and you still get extra mana out of Yurlok
If you were looking to play endurance or grinder control and you fail to find any suitable life gain then you likely have to try and do something else
It is also the cause of speculative investment in the TCG created by Richard Garfield in 1993 and distributed by Wizards of the Coast , owned by Hasbro since 2000
