Irascible Wolverine

Impulse-draw stapled to a body is old design, but plot changes the accounting on when you pay for it. The enter trigger exiles the top card and gives you the turn to spend it, which means the 3/2 arrives already having drawn you a resource; the friction is that the drawn card expires at end of turn, so you want the creature down when you have mana left to cash it. Plot is what makes that timing controllable. Pay the cost on an earlier turn, exile the card from hand, and on a later turn you drop the body without spending mana that turn, leaving the whole pool free to actually cast whatever the enter trigger digs up. It turns a two-part play (cast the creature, then play the impulse card) into a single explosive turn where the mana that would have gone to the wolverine instead goes to the card behind it. The card is a small clinic in how plot rewards front-loading: the mechanic's usual pitch is dodging a counterspell or spreading a big spell's cost across turns, but here the payoff is a mana-neutral tempo swing on the plotted turn, with the exiled card as the cherry. A 3/2 for that draws you something on the way in is a fair rate; the plot line is what pushes it past fair when the sequencing lines up.
