When the standard three-minute match timer expires and the game enters Overtime, the fundamental rules of engagement shift dramatically.

This article analyzes the absolute best cards to have in your rotation when the Overtime clock begins ticking down.
The Spell Cycle Enders
In Sudden Death, if the opponent's tower is below 1000 hitpoints, the most reliable and competitive strategy is 'Spell Cycling'.

Every top-tier competitive deck must include at least one heavy spell specifically designed to close out tight matches in Sudden Death.
The Fireball is great for chip damage, but it takes 3 or 4 cycles to kill a healthy tower in overtime.If the opponent is spell cycling you, you must pressure them so heavily they cannot afford to spend 6 elixir on a spell.Poison is risky in Sudden Death because it takes 8 seconds to deal its full damage. Instant Deployers and Bridge Threats
The opponent must guess exactly which tile he will pop up on to defend him; if they guess wrong, the Miner gets two or three guaranteed hits, which is often enough to secure the win.

In Sudden Death, speed and unpredictability are vastly superior to raw stats and massive hitpoints.
