Wargling

The two counters make Wargling a 4/4, so it can satisfy its own Ferocious condition and grant your team trample whenever it attacks.

Casting Troll Negotiations before combat turns Wargling from a 2/2 into a 4/4, so it immediately satisfies Ferocious and attacks as a 5/4 while granting trample to the team; the fight can also remove a blocker first.

Desolation Prowler can become a 4/4 before attackers are declared, enabling Wargling to get +1/+0 and grant trample to the entire attacking team.

Galion's 4 power enables Ferocious, and when both attack Galion can make another small attacker a 4/4. Wargling then gives that enlarged creature and the rest of the team trample.

Once another 4-power creature enables both cards, Scrounger's attack trigger grows the entire team while Wargling grants trample, converting the added power into substantially more damage through blockers.

Hospitality can permanently grow a creature to 4 power and enable Wargling's Ferocious attack trigger; the resulting teamwide trample makes Hospitality's accumulated +1/+1 counters much harder to chump-block.

Glóin's natural 4 power enables Wargling's Ferocious attack trigger, pumping the Wargling and granting the entire attacking team trample.
