When you put the "extra level" removal spell in your deck beyond the tier one options (Lightning Bolt, Path to Exile, Fatal Push) you are looking for some major upside, either in card advantage like Kolaghan's Command, or in versatility like Assassin's Trophy
This set had a print run of 2.6 million cards
You get to search for any land card, not just basic land
But the Tiger you are guaranteed to be able to cast on your next turn
This allows you to put your choice of a +1/+1 counter or two charge counters on up to one other target artifact, at the beginning of combat on your turn
Along with that Genesis Wave places all the land and permanents you need and usually by turn 5 theres enough mana that its worth the drop setting the following turn up for huge mana and usually can end game sacing omnath to Altar of Dementia or just simply attacking
