Dramatic Entrance

Essentially an speed undizzier for a newly played monster, it is almost impossible to prevent the Speed Summon of the played monster likely following the play of Dramatic Entrance.
It's also essentially free when used in conjunction with a grey monster and can be used on Spell Shield/Ability Shield monsters.
This effect is destroyed whenever a monster comes into play on either side, regardless if it already has Speed Summon or not. Thus, one way to prevent the opponent from utilizing it is to play a monster before they do. To do so requires an speed spell or ability that can generate a monster. Many monster creating effects are capable of doing this, but as the opponent will be expecting this (and you might not be expecting the Dramatic Entrance), it is unlikely that you will win the Clickwar.
Multiple Dramatic Entrances will have their ability stack when reducing the mana cost.
Combined with Kel'Sor Elflands, you can play a monster for a net of 2 less, as well as have it undizzied. For example, you could play a Dramatic Entrance for 1 (-1 from KE), and then a Winged Golem for 3 (-1 from KE, -2 from DE), which totals 4 instead of the normal 6.
