So this is a game called clash royale,where u have to defend your tower from enemy troops while trying to destroy thier towers with your own troops.. So in the clip the guy used a spell called rocket( u can see that ) it is one of the most expensive abilitys in the game and is really easy to miss.But it can 1 hit any troop. This costs 7 elixer( the "currency" that u use to buy troops and spells in game)
The 2 enemy troops that u see ( running on the ground) are known as elite barbarians they are really strong and difficult to counter with out a large number of troops. ebarbs cost 6 elixer.. But we see that just before the rocket hits them, the enemy who was not expecting it. Deploys another pair of ebarbs with a spell known as mirror that allows u to reuse a previous troop but with a higher cost, in this case 7 elixer for another pair of ebarbs. This shows that the enemy is really dumb/and the rocket user is very big brain. Since he wasted a really good ability and is now low in elixer.
Hopefully this helps. Also Clash royale is a fun game that u can play for free on iOS and Android
