Esika's Chariot has a tendency to snowball the game, copying tokens here and there
Alrund's Epiphany also has foretell, which is a mechanic that allows you to pay two mana to put it into exile and makes it cost only six mana in a later turn
The experience counter goes on you, the player, not on Zuko
Cloud, Midgar Mercenary Rarity: Mythic Rare TYPE: Legendary Creature SUBTYPE: Human Soldier Mercenary CMC: 2 Mana cost: USD: $28.77 EUR: 32.20 TIX: 0.59 EDHREC RANK: 1787 (2/1) When Cloud enters, search your library for an Equipment card, reveal it, put it into your hand, then shuffle
Removed from that context, I actually really like Goreclaw, Terror of Qal Sisma
It's a great one drop and tap for mana, second turn swing with your land to hit people with poison counters prior to setting up their defenses
