Since I proposed it, I'll take a whack at it. My candidate is Subodei Bahadur, an Uriankhi, and an Orlok for both Chingghis Qua Quan, and his two successors, Ugeddai Qua Quan and Guyk Qua Quan.
Subodei participated in the campaigns angainst the Keraits, Tartars, Hsia Hsia and the Chin Empire. He acted as Chingghis during the Khwaresm campaign, after initially commanding the vanguard. the operation had Subodei's fingerprints all over it: independent yet converging columns, a sweep through the Kazil Khum desert leading to an attack on the main enemy lines from far to the rear. He then, along with Jebe Noyon was tasked with pursuing and capturing the Khwaresm Shah, who had fled west. That led to a reconnaissance in force, that took the Mongols north through the Caucasus and into Ukraine . The Mongols raided the Crimea, and withdrawing east, fought an army of Russian princes at the Khalka river, destroying an army four times their size.
Subodei emerged from the Kuriltai of 1234[?] as the actual commander of the army [the nominal commander was Batu Quan, son of Chingghis' oldest son Jochi]Uggedai sent west to conquer those lands where 'Mongol ponies had trod". He was also to destroy the free roaming Kipchak [Cuman] Turks and the Volga Bulgars [who had beaten him in battle in 1224]Crossing some 15 degrees of longitude. Subodei did just that, sending the Kipchaks fleeing to Hungary. In 1237. Subodei began the conquest of the Russian principalities, in the winter, using frozen rivers as highways. By Spring the Mongols had defeated and conquered all the northern kingdoms except Novgorod [Spring floods, and they submitted]. Subodei then set his sights on Kiev. After two years fattening up their horses, the Mongols moved west, sacking Kiev in December, 1240.
Subodei then turned to eastern Europe. Using the various Mongol princes attached to his army, Subodei struck on a roughly five hundred mile front. One column drove through Trsansylvania. One invaded Poland [a feint]. Subodei and Batu led two columns across the Carpathians into Hungary.
On April 9th, 1241, the northern force under Buri [Batu's brother] and Kadaan faced an army of 40,000 under Henry the Pious at Liegnitz. They had already scattered to the wind and army under Boleslas the Chaste [where do they get thoise nicknames], and sacked Crackow. At Liegnitz, the Mongols drew out the cavalry, separating them from the infantry, using a smoke screen to obscure the latter. Then they attacked. By the end of the day, most of the 40,000 Europeans [including Henry, were dead. The Mongols, merely a feint to secure a flank, then road south, engaging Wenceslas [that Wenceslas] of Bohemia, and riding him out of aiding anyone.
The other three Mongol columns had united in front of Pest by the middle of March. They then feigned a retreat, luring an army of reportedly 100,000 north and east, to Mohi. The Mongols withdrew across a river, leaving the valley and bridge to Hungarians. The next day [April 11th], Batu launched an artillery assault with catapults and bowmen, while Subudei, downstream, built a bridge, and attacked the Hungarians from the flank and rear. When the Hungarians saw what they thought was a gap, they fled. The Mongols pursued them for three days, killing some 70,000 men. Bela IV, the king, fled for his life. The Mongols then stormed Pest, and once the Danube froze, Buda. In the Spring of 1242, Subodei had columns advancing in Italy [Udine] and Austria [they raided Wiener Neustadt], and reconned Vienna.
Then came word that Uggedai had died the previous December. Pursuant to Mongol law, and their own ambitions, most of the princes of the blood returned to Mongolia to elect his successor. the war in the West was over. Subodei went on to campaign against the Sung, and then retire. He had won some 65 battles, lost 1, and more than doubled the size of the Mongol Empire. His campaigns were well planned and coordinated. He used the newest technologies to best effect. No one else, IMHO, comes close.
