Resilient Khenra

Most eternalize designs simply hand you the same creature twice; this one hands you the same trigger twice, and the second time it hits harder. The enter-the-battlefield pump donates a creature's own power to a target, and because the token copies the printed ability rather than the original stat line, the buff scales to the token's larger 4/4 power on the encore. That size bump is exactly what the keyword rewards here: the back-half copy pumps for more than the two-mana front-half body ever could. Both triggers fire on the enter, and since eternalize activates only as a sorcery, the second coming lands on your own turn as a proactive swing-setup rather than a reactive combat save. The clever part is where the inevitability lives. Bounce, destruction, and counters answer the front half, but eternalize is the graveyard's insurance: kill the 2/2 and it feeds the encore rather than preventing it. Graveyard exile is the honest fix, since eternalize itself pays a card into exile as a cost, so once the token is made there is nothing left to answer; strip the card from the yard before that and the encore never comes. What keeps the recurring advantage from running away is the price of admission: six mana at sorcery speed turns the second copy into a deliberate midgame commitment, not a free replay. That ceiling lets a scaling combat buff with built-in follow-through sit on a modest body without warping anything around it.
