Kardur Goad Blink Of all the Goad commanders, Kardur, Doomscourge has the strongest "goad" ability despite not actually being goad: it forces your opponents to attack each other much like goad does, except it also affects creatures that enter the battlefield after Kardur's ability resolves, so your opponents can't play hasted creatures on their turn and attack you
(It enters with a +1/+1 counter on it for each color of mana spent to cast it.) At the beginning of your end step, if there are thirty or more counters among artifacts and creatures you control, this artifact deals 10 damage to each opponent
Granted not all of them are guaranteed to increase your win rate (though most of them likely would), but they are guaranteed to make your entry fee in the event effectively much cheaper

All said, Amber/Steel is an incredibly strong deck in the current Lorcana meta, and will likely be a popular combo for some time to come.
